Generalized eruptive histiocytoma is a rare form of non Langerhan's cell histiocytosis. The disease occurs mainly in adults and its etiology is still unknown. We describe a case of 48-year-old female with multiple, firm, hemispherical, redish brown papules. Lesions were distributed on the face, upper limbs and trunk. Patient's general examination and routine laboratory investigations were normal. Excisional biopsy was taken from one representative lesion. Histopathological examination revealed diffuse dermal histiocytic infiltration that was suggestive of generalized eruptive histiocytoma. Confirmatory immunohistochemical staining for CD68 antibody was done and revealed positive results. Based on clinical and histopathological criteria the diagnosis of generalized eruptive histiocytoma was established.In conclusion, we present a rare case of generalized eruptive histiocytoma which is an uncommon form of non Langerhan's cell histiocytosis. The disease does not require treatment since it is a self-healing disease.
