Conjunctival Stromal Tumor: Expansion of Findings in a Newly Described Entity

Conjunctival Stromal Tumor: Expansion of Findings in a Newly Described Entity.

Cochlear-facial dehiscence--a newly described entity.

Dehiscence of the cochlear otic capsule has recently been described as a pathologic entity. We describe two cases of cochlear-facial dehiscence, which are the first reported: a 69-year-old male who complained of hearing loss, autophony, and pulsatile tinnitus and a 41-year-old female who complained of left-sided hearing loss, pulsatile tinnitus, and vertigo. In both, computed tomography (CT) sh...

SMARCB1 (INI1)-deficient sinonasal carcinoma: a newly described entity

SMARCB1 (INI1)-deficient sinonasal carcinoma is a recently described variant of sinonasal tract carcinoma characterized by complete loss of nuclear SMARCB1 (INI1). It is very rare and currently underdiagnosed because of a lack of awareness. Before the description of SMARCB1 (INI1)-deficient sinonasal carcinomas, these tumors were probably misclassified as various malignant neoplasms. To date, o...

Primary Stromal Sarcoma of Breast: A Rare Entity

Primary soft tissue sarcomas of the breast constitute less than 5% of all soft tissue sarcomas and less than 1% of malignant breast cancers. The rarity of this tumor limits most studies to small retrospective case reviews and case reports. Primary breast sarcomas are locally aggressive tumors as evidenced by the high rate of local recurrence when excisional surgery is performed. A contemporary ...

Desmin expression by a gastrointestinal stromal tumor in a dog

This report describes the histological and immunohistochemical features of a small intestinal tumor that resembled a human gastrointestinal stromal tumor (GISTs) in a seven-year-old male cross-breed dog. This was unique because of the expression of desmin by the tumor. Grossly, the white-gray tumor measured 8.0 × 4.0 × 6.5 cm and was 760 gram in weight. It was cystic and enveloped the jejunum. ...
