We report a 39-year-old Japanese woman with a 30 x 10 mm, skin-colored, soft, hairless, irregularly elevated plaque in the left retroauricular area. Histologically, it consistently showed features of atypical hair follicles; some showed immaturely developed basaloid epithelial islands invaginated with condensed stromal cells, and others were replaced or associated with solid strands, branching cords, or lace-like networks of undifferentiated basaloid cells. Although the clinical appearance of a typical localized basaloid follicular hamartoma is a plaque of alopecia, this case seems to be a variant, because the histological findings are so characteristic of the entity. The relationship of basaloid follicular hamartoma to other hair-follicle derived tumors is also considered.

We describe a case of granuloma annulare (GA) associated with Sjögren's syndrome (SS) in a 69-year-old woman. She complained of erythematous plaques on the left forearm and neck in addition to dry eyes and mouth. The laboratory and clinical findings also fulfilled the criteria for diagnosis of SS. Histopathological examination revealed the features of interstitial type GA. It is not rare that granulomatous diseases are associated with autoimmune diseases. This case indicated that granulomatous diseases and SS are closely related and that GA should be recognized as a cutaneous manifestation associated with autoimmune diseases, including SS.
