RESUMO
We report a rare and interesting case of a combined linear, Blaschkoid and zosteriform pattern of lichen planus pigmentosus. Dermoscopy showed discrete bluish-grey dots, globules, blotches and rods against a brownish background. A skin biopsy confirmed the diagnosis from the presence of civatte bodies, melanin incontinence and band-like inflammation.

Eccrine spiradenoma is clinically characterized by a solitary, movable, tender nodule occurring most frequently on the ventral surface of the upper body. A striking symptom is paroxysmal pain. Occasionally multiple lesions may be present and may occur in a linear or zosteriform pattern. A 48-year-old female was seen with painful or tender, nomal skin colored, firm nodules distributed in a zosteriform pattern on the right thigh for 10 years, which had been slowly growing. The histopathological features were quite a characteristic of eccrine spiradenoma. We report a rare case of zosteriform network of eccrine spwadenoma occurred on the right thigh.

She describe herein two cases of eccrine spiradenoma. One is an indolent and the other is painful or tender multiple small nodules distributed in a zosteriform pattern. Histopathologically, the encapsulated lobules of the tumor are composed of two types of cells, intensely staining cells and pale staining cells, usually arranged in whorls, cords, and pseudoglands. In the second case, enzyme histochemical staining and electron microscopic examination have been done and are compared with other cases in the literature.
