Cholesterol Granuloma of the Breast Mimicking Cancer: A Case Report and Review of the Literature.

Cholesterol granuloma of the breast is an infrequent benign lesion with clinical and radiological findings suggestive of cancer. Herein, we present the case of a 52-year-old woman with no significant past medical history, who presented to the outpatient department for her routine breast screening. Physical examination revealed a painless palpable nodule in the upper external quadrant of the left breast, measuring 0.

A rare case of gastric metastasis originating from primary lung adenocarcinoma: a case report.

Unlike liver and lung, the stomach is rarely a metastatic location for cancers. We report a case of a 62-year-old man known to have lung adenocarcinoma poorly differentiated presented with melena 1 month after diagnosis. Upper endoscopy revealed an ulcerated tumor in the prepyloric antrum.

Cribriform-morular thyroid carcinoma: A case report with review of the literature.

Cribriform-morular thyroid carcinoma (CM-TC) is a rare entity that usually occurs in association with familial adenomatous polyposis (FAP) but may be sporadic. Herein, we present a new case of cribrifom-morular thyroid carcinoma occurring in a 28-year-old woman with no history of FAP.

Recurrence with lymph node and brain metastasis of an oncocytic carcinoma of the submandibular gland: A case report.

Oncocytic carcinomas of the salivary glands are rare. The submandibular gland is a rare location. It is usually associated with a poor prognosis and recurrence after treatment.

Bile duct infestation with Enterobius vermicularis diagnosed after cholecystectomy: About two case reports.

Intestinal infestation with Enterobius vermicularis is common, especially in the developing countries. However, its migration in the bile ducts is rare, often diagnosed after cholecystectomy. More investigations are needed to define its involvement in symptoms presented by patients and the likelihood of complications.

[Sclerosing rhabdomyosarcoma of the parotid gland: Unusual location of a rare mesenchymal tumor].

Rhabdomyosarcoma is a malignant mesenchymal tumour with skeletal muscle differentiation. Its sclerosing variant is a rare entity, which is described in the latest WHO edition of soft tissues in association with the spindle cell subtype, with which it shares clinical, morphological and cytogenetic features. Cytogenetic advances have allowed a prognostic approach to fusiform/sclerosing cell rhabdomyosarcoma by individualizing 3 different genomic prognostic groups.

Metatypical Basal Cell Carcinoma: A 6-Year Retrospective Study.

Metatypical basal cell carcinoma (MBCC) represents a high-risk type of cutaneous tumor and has characteristics similar to basal cell carcinoma and squamous cell carcinoma. We report a retrospective study of 13 patients who presented with cervicofacial MBCC. Our study found an increased prevalence of aggressive clinicohistologic features and showed disease recurrences in more than one-third of the patients; therefore, we conclude that MBCC is an aggressive variant that requires a complex surgical approach for achieving a stable and complete remission.

HHV8/EBV Coinfection Lymphoproliferative Disorder: Rare Entity with a Favorable Outcome.

HHV8/EBV-associated germinotropic lymphoproliferative disorder (GLD) is a challenging diagnosis given its rarity, the particular clinical presentation, and the lack of expression of markers usually used in establishing hematopoietic lineage. We report a new case of HHV8/EBV GLD in an immunocompetent 78-year-old woman. The diagnosis was made in an incidentally discovered lymphadenopathy.

[Primary peritoneal yolk sac tumour. A case report].

Yolk sac tumours are rare germinal neoplasms that often arise in ovary and testis. Extragonadal localisations such as mediastinum, retroperitoneum, brain and vagina are uncommon. Primary intraperitoneal tumours are exceedingly rare.
