RESUMO
Objective: Syringoma is a benign adnexal neoplasm of sweat gland, usually presenting as extra-genital lesions, while vulvar localization is rare. Moreover, syringoma is an uncommon vulvar neoplasms. Case report : A 44-year-old woman with previous diagnosis of duodenal gastrointestinal stromal tumour, underwent a local surgical excision for an isolated, painful, vulvar lesion. The specimen was submitted for histological examination. A vulvar syringoma was diagnosed. Conclusion: We describe this case according on its rarity and atypical presentation as well; therefore, vulvar neoplasms encompass many differential diagnoses, among which the incidence rate of syringoma is very low. Although its rarity, syringoma should be included among the differential diagnosis for vulvar neoplasm.
RESUMO
We report a case of a 38-year-old man affected by the human immunodeficiency virus (HIV) with a diagnosis of Castleman's disease, plasmablastic type human herpes virus 8 infection, and Kaposi sarcoma based on a histological examination of one cervical lymph node biopsy. The patient underwent (18)F-2-fluoro-2-deoxyglucose positron emission tomography/computed tomography ((18)F-FDG-PET/CT). (18)F-FDG-PET/ CT seems to be a valuable tool in patients with HIV-associated Castleman's disease and Kaposi sarcoma. It allows accurate staging and identifies more sites of disease than conventional CT.

Syringotropic cutaneous T cell Lymphoma (SCTCL) is a rare localized variant of CTCL. It is characterized by erythematous papules that, at histological examination, show dense dermal infiltrates of atypical T cells, that are preferentially located around hyperplastic eccrine sweat glands and ducts, with absent or minimal epidermotropism. Its relationship with mycosis fungoides and other CTCLs is not clarified and is still under discussion. Several treatment approaches have been suggested, but therapeutic results are often disappointing. We report the case of a patient with typical clinical and histopathological features of SCTCL and an excellent response to PUVA therapy.
