Abstract
- Nodular scabies is a clinical variant of classic scabies with uncertain cause. The cutaneous manifestations consist of firm, erythematous nodules focally affecting genitalia, groin and axillae, and no case of generalized involvement has been reported in the literature. On histopathologic examination, mites and excretas were known to be seldom found in the stratum corneum, but if serial sections are studied, they can be seen in as much as 20% of the cases. The dermis shows dense superficial and deep perivascular mixed cell infiltration composed of lymphocytes, histiocytes, plasma cells, eosinophils, and atypical mononuclear cells, which should be distinguished from many types of lymphomas. We herein report a case of nodular scabies that clinically affected whole body and histopathologically revealed mite and eggshells in the stratum corneum and perivascular mixed cell infiltration throughout the dermis.
