Context: Epithelioid and epithelial neoplasms seen in bone are rare and include epithelioid variants of vascular lesions, osteoblastoma, osteosarcoma, chordoma, and chondroblastoma as well as adamantinoma and metastatic carcinoma.
Objective: To provide an overview of tumors with epithelioid histology and address the clinical context and diagnostic issues.
Data Sources: Pertinent literature is reviewed with emphasis on recent and controversial issues.
Conclusions: The differential diagnosis in epithelioid/epithelial lesions of bone is limited. The primary consideration in many cases is distinguishing primary from metastatic lesions.

Primary cutaneous rhabdomyosarcoma with EWSR1/FUS::TFCP2 fusion: four new cases with distinctive morphology, immunophenotypic, and genetic profile.

EWSR1/FUS::TFCP2-rearranged rhabdomyosarcoma (RMS) is a rare tumor with an aggressive clinical course, a predilection for craniofacial bones, spindled and/or epithelioid histomorphology, and positive immunohistochemistry (IHC) for epithelial and myogenic markers, along with variable ALK expression. Herein, we present four additional cases of primary cutaneous TFCP2-rearranged RMS. Notably, one tumor (case 1) displayed a varied pathological spectrum, initially presenting as a low-grade spindle cell neoplasm, but progressed into a high-grade spindle/epithelioid tumor.

fusion-positive sarcomas constitute an emerging subtype of undifferentiated sarcomas, histopathologically composed of epithelioid and spindle cells. We describe two fusion-positive sarcomas occurring in the occipital region of a 53-year-old female patient and the left shoulder of a 25-year-old male patient. Histopathologically, the former tumor comprised spindle and polygonal-shaped/epithelioid cells, while the latter comprised epithelioid cells.

Solitary fibrous tumors (SFTs) of the central nervous system (CNS) are rare mesenchymal tumors characterized by a fusion of the NGFI-A-binding protein 2 (NAB2) gene and the signal transducer and activator of transcription 6 (STAT6) gene, immunohistochemically resulting in nuclear expression of STAT6 - an immunohistochemical hallmark essential for diagnosis, as outlined in the fifth edition of the World Health Organization Classification of Tumors. Dedifferentiation, where low-grade tumors transform into high-grade forms, has been observed in SFTs, with documented cases involving sarcomatous or rarely epithelial transformations. We report the first case of a CNS SFT exhibiting "transdedifferentiation" into epithelioid neuroendocrine differentiation.

Soft tissue tumors with EWSR1/FUS fusion to genes encoding the cyclic adenosine monophosphate response element-binding (CREB) transcription factor family (ATF1, CREB1, and CREM) are rare and heterogeneous aggressive tumors, often found in the peritoneal cavity. Here, we report two cases of malignant epithelioid tumors with EWSR1::CREB fusion involving the kidney in females in their 30 s. Both tumors appeared as solitary masses, measuring 5.

Introduction: Perivascular Epithelioid Cell tumor (PEComa) is a rare mesenchymal neoplasm characterized by the co-expression of melanocytic and myoid markers. While PEComas can arise in diverse anatomical sites, gastric PEComas are exceedingly rare, with merely nine cases documented in the extant literature.
Case Presentation: Herein, we have presented a case of gastric PEComa in a 65-year-old male patient who exhibited a 3-year history of epigastric pain, with notable exacerbation in the two months prior to diagnosis.
