Cutaneous colesional acquired immunodeficiency syndrome associated Kaposi sarcoma and cryptococcosis.

The clinicopathologic features of 4 AIDS patients with cutaneous colesional Kaposi sarcoma (KS) and cryptococcosis, a rare phenomenon, are described. Biopsies from 3 patients who were highly active antiretroviral therapy (HAART)-naive demonstrated predominant KS with a conspicuous spindle cell component and small aggregates of cryptococcal yeasts in 2 biopsies and predominant gelatinous cryptococcosis with attenuated KS spindle cells in 1 biopsy. One patient was HAART exposed.

Gastric plexiform angiomyxoid myofibroblastic tumor.

Plexiform angiomyxoid myofibroblastic tumor (PAMT) is a relatively recently described gastric tumor with a peculiar plexiform growth pattern. PAMT is typified by a myofibroblastic immunophenotype that distinguishes it from the more common gastrointestinal stromal tumors and the rarely documented fibromyxomas. We report an additional PAMT, the seventh tumor with this label, which was an incidental finding on abdominal computed tomography scan of a 35-year-old Indian female.

Granulomas in acquired immunodeficiency syndrome-associated cutaneous Kaposi sarcoma: evidence for a role for Mycobacterium tuberculosis.

Background: Co-lesional acquired immunodeficiency syndrome-associated cutaneous Kaposi sarcoma (AIDS-KS) and Mycobacterium tuberculosis-associated granulomatous inflammation are undocumented.

Method: Retrospective appraisal of skin biopsies with co-lesional AIDS-KS and microscopic tuberculosis (TB).

Results: Sixteen biopsies from nine males and seven females form the study cohort.
