Pseudogaucher cells in cutaneous Mycobacterium avium intracellulare infection - Report of a case

We report on a patient infected with human immunodeficiency virus, and with cutaneous Mycobacterium avium intracellulare, in whom many cells with abun dant reticulated cytoplasm resembling the characteristic cells of Gauchers disease ("pseudogaucher cells") were noted within the dermal infiltrate on biopsy. Although pseudogaucher cells have been reported in association with M. avium intracellulare infection in extracutaneous sites, this is, to our knowledge, the first report of cutaneous pseudogaucher cells in the skin.
