Biphenotypic lung carcinoma with coexpression of TTF-1 and ΔNP63/P40 within most of the same individual cells: a further case confirming poor prognosis and a review of literature
Pathologica. 2024 Feb;116(1):13-21. doi: 10.32074/1591-951X-957.ABSTRACTThe WHO Classification of Tumors, Thoracic Tumors, 5th edition, has outlined the use of TTF-1 and ΔNP63/P40 to discriminate between adenocarcinoma and squamous cell carcinoma. In 2015, the first description of a rare non-small cell lung carcinoma featuring co-expression of glandular and squamous differentiation within most of the same individual tumor cells was reported on, with ultrastructural and molecular demonstration of such a biphenotypic differentiation. We herein describe an additional case of this rare tumor entity, which is confirmed to be a...

Changes in breast cancer grade from biopsy to excision following surgery or primary chemotherapy
CONCLUSIONS: The reversal of M and G underestimation in CNB to "overestimation" in the PST group can only be explained with the effect of mitosis reduction following chemotherapy. Whether the posttreatment decrease in G reflects any prognostic value remains to be elucidated.PMID:38482672 | PMC:PMC10938276 | DOI:10.32074/1591-951X-958 (Source: Pathologica)

Soft tissue tumours of the penis. The 30-year Istituto Nazionale Tumori di Milano experience
CONCLUSIONS: Among sarcomas of the genitourinary tract, tumours of the soft tissues of the penis are the rarest. Penile sarcomas can present at a young age. Kaposi's sarcoma in HIV-negative patients has a favorable outcome, while deep sarcomas have an aggressive behavior and poor prognosis.PMID:38482674 | PMC:PMC10938274 | DOI:10.32074/1591-951X-953 (Source: Pathologica)

TROP-2, NECTIN-4 and predictive biomarkers in sarcomatoid and rhabdoid bladder urothelial carcinoma
CONCLUSION: Sarcomatoid and rhabdoid BUC do harbor positive expression of the ADC targets TROP-2 or NECTIN-4 in a relatively modest subset of cases, whereas the majority do not. Different combinations of other positive biomarkers may help the choice of medical therapies. Overall, these findings have important clinical implications for targeted therapy for BUC.PMID:38482675 | PMC:PMC10938277 | DOI:10.32074/1591-951X-937 (Source: Pathologica)

Pleomorphic/solid lobular carcinoma of male breast with PALB2 germline mutation: case report and literature review
Pathologica. 2024 Feb;116(1):62-68. doi: 10.32074/1591-951X-936.ABSTRACTMale breast cancer (MBC) accounts for approximately 1% of all breast cancers and among these infiltrating lobular carcinomas (ILC) represents only 1-2% of all MBC cases. Pleomorphic invasive lobular carcinoma (PILC) is an aggressive variant of ILC with only eight cases reported until now in males. Up to 10% of MBC cases have a germline pathogenic variant in a predisposing gene such as BRCA1 and BRCA2 genes. Mutations in PALB2 (partner and localizer of BRCA2) have been reported in men with breast cancer, with a frequency that ranges from 0.8 to 6.4%, bu...

Testicular metastasis of prostate adenocarcinoma: the other side of orchiepididymitis
CONCLUSION: Although metastatic prostate adenocarcinoma is rare, a correct diagnosis is of paramount importance because the therapy changes accordingly. Patients who complain of scrotal pain need to be examined accurately. Although the most common cause behind this symptom is infectious, the patient's past medical history should be reviewed to exclude previous malignancies.PMID:38482677 | PMC:PMC10938275 | DOI:10.32074/1591-951X-940 (Source: Pathologica)
