[Sebaceous cutaneous carcinoma. Value of early cytological test].

Sebaceous carcinoma is a skin tumour which frequently metastases to the visceral organs. Needle biopsy is needed for rapid diagnosis. We observed a case in a 65-year-old patient who had a tumour formation below the right maxillary angle and homolateral justamandibular lymph node enlargement. Cytology of the needle biopsy showed a double cell population: small anaplastic cells and an agglutinated cell mass with peripheral maturation and sebaceous differenciation. Treatment was surgical with homolateral node dissection and secondary plasty. The tumour was large, non-encapsulated with local infiltration. On light microscopy, two cell populations were seen. Evident sebaceous differentiation was confirmed by histochemical staining. Immunolabelling confirmed the epithelial nature of the tumour. The clinical diagnosis of sebaceous carcinoma is difficult. Early cytology is needed to identify the two cell components when other cytological signs do not allow a positive diagnosis.

[Cryptococcal chorioretinitis and acquired immunodeficiency syndrome: apropos of a case].

A patient with acquired immune deficiency and antecedents of pancreatitis presented with headaches, fever, dyspnea and bilateral decrease of vision. A diagnosis of disseminated cryptococcosis was made by lumbar puncture, alveolar washing and elevated cryptococcal antigen in blood, urine and stool. Bilateral chorioretinitis with ischaemic maculopathy was responsible of the low vision and attributed to cryptococcal infection after vitreous puncture and isolation of yeast from the vitreous. Systemic treatment with Amphotericin led to resolution of the chorioretinitis. A retinitis due to cytomegalovirus was associated short time before the patient died. Post-mortem anatomopathologic analysis revealed cryptococcus in high number in the choriocapillaris.

Primary neutrophil-rich, CD30-positive anaplastic large cell lymphoma of the stomach: case report and review of the literature.

Primary T-cell lymphoma of the stomach is a rare disease, most gastric lymphomas being of B-cell type. Here we describe a unique case of primary neutrophil-rich CD30-positive anaplastic large cell lymphoma (ALCL) of the stomach that was treated and cured by combined chemotherapy. According to our literature review, only 7 cases of primary gastric ALCL have been previously reported, none of them being of the neutrophil-rich subtype. Although very peculiar in its histological presentation, which may simulate an inflammatory or carcinomatous process, the natural history as well as the clinical features of this unusual gastric lymphoma does not differ from the other reported cases of gastric ALCL.
