Wf. Ng et Kt. Loo, CUTANEOUS CRYPTOCOCCOSIS - PRIMARY VERSUS SECONDARY DISEASE - REPORT OF 2 CASES WITH REVIEW OF LITERATURE, The American journal of dermatopathology, 15(4), 1993, pp. 372-377
The clinical, immunological, and pathological features of solitary cut
aneous cryptococcosis in two apparently healthy Chinese adults are rep
orted. In patient 1, regional cryptococcal lymphadenopathy also occurr
ed. Both patients showed lymphopenia with a proportionate decrease in
T-helper and T-suppressor cells. Both skin and lymph node biopsies sho
wed granulomatous inflammation and the presence of cryptococcus. A cha
ncriform syndrome developed in patient 1, indicating primary cutaneous
cryptococcosis. Chancriform syndrome is rare in cryptococcal skin inf
ection, probably due to immunosuppression in susceptible patients. In
patient 2, the deep dermal and subcutaneous inflammatory involvement a
nd anatomic location of the lesion on the upper medial thigh are suppo
rtive of secondary skin disease. Unless negated by a reliable history,
the following features are indicative of secondary disease: inflammat
ion centered in deep dermis or subcutaneous fat, lesion on covered par
ts of body, and multifocal skin lesions. Some cases remain unclassifia
ble. In practice the distinction between primary and secondary cutaneo
us cryptococcal disease is not essential because less toxic, effective
antifungal drugs are now available.
