Clinical symptoms are varied with possible metastasis to the regional lymph nodes or lung. Radiographically, it usually manifests as an ill‐defined osteolytic radiolucency. Histologically, it resembles ameloblastoma that is mostly devoid of its familiar microscopic features in combination with prominent cytological atypia and mitotic activity. A rare and atypical presentation of ameloblastic carcinoma of the mandible with unconventional clinical and radiological features is documented in this case report.

A 67‐year‐old man visited our hospital for further evaluations due to gastric adenocarcinoma. The gastric cancer was located in the prepyloric area and appeared to be a protruding mass with an infiltrative growth pattern. Initial pancreatic and postoperative hepatic and pulmonary metastases were detected radiologically. Microscopically, choriocarcinomatous and hepatoid differentiation was observed with a moderately differentiated adenocarcinoma. The choriocarcinomatous components were positive for β‐hCG and the hepatoid components were positive for α‐fetoprotein (AFP). These uncommon pathological patterns are supposed to arise from the retrodifferentiation pathway of primary gas...

Computed tomography scan showed a mass lesion in the left CP angle, which was excised. Biopsy was suggestive of melanoma due to abundance of melanin. After 12 years, he had local recurrence and was re‐operated. On reviewing the previous and later biopsy, final diagnosis of melanocytoma was made because of additional finding of absence of mitosis and macronucleoli, which were overlooked in the previous biopsy. Awareness of this finding reduces the possibility of diagnostic error in melanotic tumors. Reliance on the presence of abundance of melanin as the sole criterion for diagnosing melanoma resulted in erroneous diagn...

We retrospectively analyzed all histopathology reports of nephrectomy specimens and renal biopsies from our department in the last year. Three patients of isolated renal mucormycosis were identified. All three patients presented with acute abdomen and renal failure. None had a preceding known predisposing disease for mucormycosis. Ante mortem diagnosis was made in one patient. Fungal culture was positive in one case. We emphasize that isolated renal mucormycosis may affect immunocompetent host and greater clinical suspicion is required for prompt treatment in view of poor prognosis associated with renal mucormycosis.

Frozen section examination of the first specimen was diagnosed as low grade mesenchymal tumor. Formalin fixed paraffin section histology revealed composite tumor composed of three characteristic histologic components: epithelioid, ganglion, and spindle cell. Immunohistochemistry tumor cells were positive for neuron specific enolase, synaptophysin, chromgranin, S100, and neurofilament protein. Cytokeratin and bcl‐2 were focally positive. Single mitotic figure was noted. Ki67 labeling index was < 3–4%. In the subsequent pancreaticoduodenectomy specimen, there was no residual tumor in the periampullary area. We discuss the differential diagnosis and review the current published litera...

The histological features of secretory carcinoma are reminiscent of normal early secretory endometrium (17–22 days), displaying a well differentiated glandular pattern having columnar cells with subnuclear or supranuclear vacuolization containing clear glycogenated cytoplasm. It is extremely important to distinguish secretory carcinoma from clear cell carcinoma in view of the excellent prognosis of the former and the unfavorable prognosis of the latter.

A 65‐year‐old man was admitted with left lung mass and left upper abdominal pain. A biopsy was performed for the lung mass under suspicion of malignancy. Microscopic examination demonstrated the proliferation of spindle cells, fibrosis and heavy infiltration of plasma cells, which were strongly immunoreactive for IgG4. Diffusely enlarged pancreas in abdominal computed tomography scan and elevated serum IgG4 level suggested the patient also had an autoimmune pancreatitis. We concluded this patient had the pulmonary inflammatory pseudotumor, as well as the autoimmune pancreatitis. These features were manifestations of the so‐called IgG4‐related sclerosing disease, which ...

The mesenteric LAM is a quite unusual presentation. A 47‐year‐old woman was admitted to our hospital with a 7‐year history of abdominal mass. A computed tomography showed a well marginated mass with soft tissue attenuation. Laparoscopic excision was performed. The specimen revealed a well circumscribed dark cystic mass. The cut surface showed a thin walled cystic tumor with haphazardly distributed trabeculated septa. Microscopically, the tumor showed variable sized ectatic spaces lined by flattened endothelial cells and surrounded by epithelioid or spindle‐shaped cells. The lining...

Clinically, it presented as a mucocele‐like lesion. An excised specimen showed a well‐circumscribed, 1.3 cm × 1.0 cm × 0.8 cm‐sized, yellowish mass, composed of blood vessels, smooth muscles and mature adipose tissues. These were not epithelioid cells and immunohistochemical stain for human melanoma black (HMB)‐45 was negative. Extrarenal AML usually is not associated with tuberous sclerosis and has no HMB‐45 immunoreactive cells although it shares the terminology with renal AML. It is regarded as benign. Surgical excision is considered curative.

Mean AgNOR counts (mAgNOR), proliferative index (pAgNOR), variation in size and dispersion of AgNOR dots in cells were graded and compared in normal, dysplastic, primary and metastatic squamous cell carcinoma (SCC). The Ki67 percentage is significantly increased from normal squamous to SCC group, and the reactivity of staining were related to histological differentiation. The mAgNOR counts were high in all 44 cases of primary and metastatic SCC and low in normal squamous tissue and increased in dysplastic lesions. The mAgNOR count in SCC increased from well di...

The tumor in case 1 could not be completely excised due to its huge size and massive destruction of the bilateral maxilla. The tumor in case 2 was completely excised through staged operations. Tumors in both cases were diagnosed as juvenile pammomatoid cement‐ossifying fibroma by the histology. Here, we report two cases from Korea and describe psammomatoid morphology and how to differentiate it from other fibro‐osseous lesions.

This tumor is thought to arise from bronchial submucosal glands distributed throughout the lower respiratory tract. We recently experienced a case of epithelial-myoepithelial carcinoma of the bronchus in a 61-year-old man. Computed tomography of his chest revealed an endobronchial mass in the bronchus of the left lower lobe. The lobectomy specimen showed a solitary endobronchial mass, measuring 2.3 cm in greatest diameter.

She presented with mature teratoma of the ovary, which contained well formed, grossly visible prostatic gland with a central urothelium-lined duct resembling a urethra. Mature teratomas are characterized by the presence of tissues derived from the embryonic layers of ectoderm, mesoderm, or endodermal lineage. However, prostatic tissue is a very unusual component of teratomas. The rare existence of prostatic tissue in a mature teratoma can be explored through three feasible pathogenetic theories. These origins include teratomatous monodermal differentiation, developmental abnormality, or metaplasia. The coexistence of rare prostatic tissue with a rare central urethral duct in a mature teratoma makes thi...

For the majority of early gastric cancers without nodal involvement, endoscopic mucosal removal (EMR) is safer and more cost-effective than are other treatment methods. Here we report a rare case of differentiated mucosal carcinoma with extensive lymphovascular invasion and lymph node metastasis. Endoscopy showed a 5.5 cm non-ulcerated slightly elevated and depressed lesion without indication of submucosal involvement. Although the tumor met the extended criteria for EMR, D2 gastrectomy was performed. The resected specimen showed a 5.5 cm intramucosal carcinoma with extensive lymphovascular invasion of the submucosa, and metastasis to two perigastric nodes, indicating that metastasis can occur in patient...

This tumor is commonly involved within the gastrinoma triangle. Herein we report a peripancreatic lymph node gastrinoma in a 56-year-old man who was suffered from a recurrent duodenal or jejunal ulcer perforation. Octreotide scan detected a peripancreatic or periduodenal mass and the serum gastrin level was set in upper normal range (107.73 pg/mL). Whipple's procedure was performed. The resected specimen showed multiple duodenal ulcers, hypertrophic gastric body mucosa and an enlarged peripancreatic node, measured 1.5 × 1.0 cm in cross diameter.

The patient underwent right hemicolectomy with small bowel segmental resection. Microscopically, the tumor masses were characterized by incohesive sheet of neoplastic cells with vesicular nuclei, large nucleoli, and abundant eosinophilic cytoplasm. Immunohistochemical studies showed strong reactivity of the tumor cells for pan-cytokeratin, anti-endomysial antibodies (EMA) and vimentin. This was a case of undifferentiated carcinoma with prominent rhabdoid feautures arising in the ascending colon with multiple gastrointestinal metastases.

However, various complications associated with the use of activated charcoal have been reported, with acute respiratory failure being a fatal one. In the presenting case, a 29-year-old female arrived at an emergency room having taken an overdose of drugs. When a nasogastric tube was inserted for gastric lavage and charcoal administration, she vomited and respiration ceased. The patient subsequently developed acute respiratory failure and died 19 days after admission. Charcoal deposition in the trachea, bronchi and lungs was observed on the postmortem examination.

It usually can be seen in the lateral wall of the cervix uteri. In males, the mesonephric remnants are seen in epididymis and efferent ductules. Prostate is one of the rare locations, on which the mesonephric remnants can be found. Hyperplasia of mesonephric remnants of prostate is rare but important because sometimes it is difficult to differentiate from adenocarcinoma. The lesion is important in the differential diagnosis from the high grade prostatic intraepithelial neoplasia. Here, we report an additional case of mesonephric hyperplasia, epididymal type, in a 66-year-old man.

The physician tried to biopsy a submucosal mass-like lesion with tortuous and exaggerated submucosal blood vessels. Massive bleeding occurred due to iatrogenic injury. Isolated gastric varices are less prevalent than esophageal varices, but it has a higher motality rate because of the difficulty of controlling bleeding. Physicians should be mindful of isolated gastric varices, especially during examination of those with liver cirrhosis.

Practical guidelines are needed for forensic autopsy practice in cases of natural unexpected deaths due to ischemic heart disease or other cardiovascular diseases in Korea. An evaluation of the clinical history is the first step, including the collection of all available information on the subject. As a standard autopsy procedure, every subsystem of the heart and vessels should be thoroughly studied including the coronary arteries, the myocardium, the cardiac valves, and the conducting system. In addition, histological, toxicological, biochemical and molecular analysis need to be applied to the detection of myocardial infarction from the medico-legal point of view. Also important is the asses...

Fine needle aspiration of breast nodules showed a cellular smear with relatively homogenous, poorly cohesive tumor cells in a relatively clean background. The tumor cells were round to oval, with hyperchromatic nuclei, abundant cytoplasm and plasmacytoid in appearance. A few amorphous materials, possibly amyloid, were also noted. The patient underwent radical thyroidectomy, cervical lymph node dissection and excision of breast nodules. The primary thyroid mass was typical of MTC but metastatic breast tumors showed more homogenous and smaller tumor cells. The cellular origin of the breast tumors was confirmed by their immunoreactivity for calcitonin, chromogranin, synaptophysin and TTF-1...

Metastases usually become clinically apparent within 18[ndash]24 months of diagnosis, though they can develop as many as 30 years after primary tumor removal. The most common metastatic sites are the peritoneal surface and the liver. Pulmonary metastases are less common (approximately 7% of all metastises). Here, we report a case of pulmonary metastasis of a GIST of the rectum. A 50 year-old-woman, having received a Miles' operation for GIST of the rectum 10 years previous, was found to have a tumor in the right lung during a follow-up examination. A 2.5 cm sized well-demarcated mass presented in her lung parenchyma. The tumor was composed of spindle and epithelioid cells showing diffuse and...

Since sildenafil (Viagra[trade]) has been introduced in 1998, there are more concerns on the safety issue of sildenafil and sexual activity as a forensic determination of the cause of death in those cases. We have collected 68 cases of sudden death occurred within 24 hours after sexual intercourse among 13,824 cases for five years from 2001 at the head office of the National Institute of Scientific Investigation in Seoul, Korea. There were 59 men and 9 women (M:F = 6.6:1). The most common cause of death was ischemic heart disease (20 in 68, 29.4%) in both men and women. Sildenafil (Viagra[trade]) was detected in blood in 8 men and only in gastric content in 2 men (10/59, 17.0%). The level in...

It is frequently confused with chronic diffuse sclerosing osteomyelitis (CDSO) in the literature. Two cases of FCOD are examined to determine the characteristics of their calcifying tissues. The first case was non-infected, while the second case was severely infected, displaying the typical features of CDSO in clinico-radiologic findings. The infected FCOD case showed large bacterial colonies in the main lesion with rare inflammatory reaction. The globular cementum-like materials of FCOD looked like woven bone and showed increased positive reaction to Alcian blue stain, of which peripheral margin was strongly positive for the antibody of ameloblastin,...

Grossly, the mass was well circumscribed, unencapsulated, soft to rubbery, oval shaped and measured 11.0 cm at its greatest diameter. The cut surface showed multinodular whitish-gray to tan solid appearance. Microscopically, the tumor revealed a wide spectrum of histologic features with alternating hypercellular and hypocellular areas, patternless architecture, haphazard arrangement of oval to spindle cells, branching vessels with perivascular hyalinization, frequent keloid-like collagen deposits and stromal hyalinization. Multifocal hypercellular areas revealed moderate to marked cytologic atypia and frequent mitotic figures with atypical mitoses.

They presented with fever, lymphadenopathy, and eruptions on the skin of palm and face. Each patient had a lymph node biopsy which showed the typical necrotizing lymphadenitis of KD. Skin biopsies from the two patients showed various pathologic findings of a crusted epidermis, a dense lymphohistiocytic perivascular and interstitial infiltrate, and abundant karyorrhectic debris with an absence of neutrophils, paralleling the nodal histology in KD. Immunohistochemically, the lymphohistiocytic cells in the skin and lymph nodes showed similar positivity for CD68, CD3, CD8, granzyme B and negativity for CD20 and CD4. These findings suggest that the cytotoxic T lymphocytes play important ro...

Continuous chronic liver damage leads to a progressive accumulation of scarring proteins and finally, alters normal tissue structure and function by inducing fibrosis, cirrhosis and ultimately liver failure. Despite the considerable evolution on the study of liver fibrosis and cirrhosis during the past decade, a full understanding of liver fibrosis and cirrhosis still remains a goal for scientists. Although liver fibrosis and cirrhosis is mediated by various cytokines including tumor necrosis factor-alpha, interleukin-10 and transforming growth factor-beta (TGF-[beta]), it has been shown that TGF-[beta] plays the most significant role in chronic liver disease. In early liver injury stage, TGF-[beta] i...
