ABSTRACT
Churg-Strauss syndrome (CSS) is an uncommon disorder that is characterized by asthma or allergic rhinitis, fever, systemic vasculitis, extravascular granulomas and hypereosinophilia. Cutaneous manifestations of CSS are one of the most common extra-pulmonary findings, and they occur in approximately 60% of the cases. Other manifestations include pulmonary infiltrates and heart, kidney, gastrointestinal tract, peripheral and central nervous system involvement and the patients also complain of systemic symptoms, including malaise, fever, myalgia and weight loss. The diagnosis of CSS is difficult because the manifestations vary with the disease stage and delayed treatment can lead to fatal major organ damage. We report here on 3 cases of CSS that were first diagnosed by the dermatologic department and with consultation from other departments. So, we want to remind dermatologists that if the patients of asthma or other allergic diseases have purpuric skin lesion, then CSS should be included in the differential diagnosis.

Pigmented spindle cell nevus (PSCN) is a solitary heavily pigmented macule or papule that usually occurs on the lower legs of women in the second decade of life. Histologically, fascicles of uniform, elongated, pigmented nevoid cells at the dermo-epidermal junction tend to fuse with neighboring nests. PSCN should be differentiated from Spitz nevus, dysplastic nevus, and malignant melanoma. For making the differential diagnosis of PSCN from malignant melanoma of nevoid cells, the overall symmetry, relative uniformity, maturation with depth and no nuclear atypia are important clues. A 3-year-old girl presented with a black papule on the anterior aspect of the ankle. We diagnosed PSCN by the histologic findings and the specific "starburst" dermoscopic pattern.
