In October 1987, a 23 years old Black female was first seen at the General Hospital in Port of Spain, Trinidad, for tinea corporis and tinea unguium mycosal infection affecting both hands and feet. In addition, she was also discovered to have a generalized exfoliative erythematous, pruritic rash, which was heavily infected with the mites of Sarcoptes scabiei. Her glucose tolerance test and full blood count were normal and she was treated approoriatelv for both tinea and scabies. During the ensuing 4 iears she was repeatedly admitted to the dermatology unit for treatment of crusted scabiesand tinea corporis. In August 1990 the crusted scabiesbecameintractable, and the patient was admitted to the medical ward for further evaluation. The generalized exfoliative, erythematous, pruritic rash was prominent. She had no obvious palpable lymph node. Her white blood cell count was 25~ 109/L, with segmenters 29%, lymphocytes 43%, monocytes 9%, eosinophils 6%, and atypical lymphocvtes 13% (lvmnhocvtes with clover leaf-like nuclei). She was seronegati

1987). Persons infected with the virus have been known to becomeimmunodeficient and to develop opportunistic infections such asPneumocystis carinii pneumonia, candidiasis, and hyperinfestation with Strongyloides stercoralis (SATO et al., 1982; NAKADA et al., 1987). There are a few recent repotts of crusted scabiesoccurring in patients infected with HTLV-1 infection (SUZUMIYA et aE., 1985: FLETCHER et al., 1992). Crusted (Norwegian) scabieshas been known to occur in the immunocompromised patient (PATERSON et aZ., 1973; LA GRENADE, 1981; YARBROUGH & IRIONDO, 1987; SIRERA et al., 1990). In regions where HTLV-1 is endemic, crusted (Norwegian) scabiesshould alert clinicians to the possibility of underlying HTLV-1 infection and/or smouldering adult T cell leukaemia’lymphoma, as was evident in this patient. With the rise in incidence of scabiesin the Caribbean, it may become mandatory to screen scabetic patients not only for nephrotoxigenic streptoccocus but also for HTLV-1 (REID, 1988; REID et al., 1990) in order to try to stem the transmission of this retrovirus and its devastating diseasecomplex.
