Primary Esophageal Melanoma with Aberrant CD56 Expression: A Potential Diagnostic Pitfall
Primary esophageal malignant melanoma (MM) is rare and extremely aggressive. For pathologists, it can be challenging to diagnose and differentiate from other poorly differentiated malignant neoplasms in the esophagus. Complicating this fact, MM can have divergent differentiation and express nonmelanocytic immunohistochemical markers including epithelial markers (cytokeratins) and rarely neuroen...
متن کاملSoft-tissue textiloma: a potential diagnostic pitfall.
Klippel–Trenaunay syndrome has 3 essential features: cutaneous hemangiomas, varicose veins and hypertophy of the involved limbs in length or girth, or both. Both bones and soft tissue are usually affected by the hypertrophy. The arteriovenous malformation effects are polysystemic. Patients with this syndrome are at risk of thromboembolic disease. Baskerville’s report shows that 7 (14%) of 49 pa...
متن کاملPrimary endometrioid adenocarcinoma of the cervix with widespread squamous metaplasia – a potential diagnostic pitfall
BACKGROUND Uterine or endocervical biopsies that contain endometrioid adenocarcinoma with widespread squamous metaplasia are usually of endometrial origin. The presence of squamous metaplasia is said to be helpful in distinguishing endocervical from endometrial adenocarcinomas in small biopsy samples. CASE PRESENTATION A 51-year-old woman presented with post-coital and post-menopausal bleedin...
متن کاملMyxofibrosarcoma: A Diagnostic Pitfall
Myxofibrosarcoma (MFS) is a variant of the group of malignant fibrous histiocytomas. It is one of the most aggressive types of soft tissue neoplasms. The clinical presentation is not pathognomonic and the histological aspects are highly heterogenous, frequently delaying the diagnosis or leading to misdiagnosis. Complementary histochemical and immunohistochemical stainings are mandatory to achie...
متن کاملCytokeratin positivity in myxopapillary ependymoma – a potential diagnostic pitfall
BACKGROUND Myxopapillary ependymomas (MPE) occur in the filum terminale of the spinal cord, but also present in extra-spinal locations such as subcutaneous tissue and brain. They are slow growing grade I gliomas. Areas of solid growth pattern with aggregates of cells with "epithelioid morphology" seen in MPE can mimic metastatic carcinoma. The presence of occasional cells with clear cytoplasm a...
