Trichofolliculoma is a
rare tumour, presenting as a facial papule with central hairs on the scalp,
face, neck and vulva of adults. Recently, dermoscopic examination has proven
valuable in a great number of dermatological diseases. Easy-to-guess dermoscopic
patterns differ according to the variability and duration of the lesion in
cases of trichofolliculoma. Recently, two dermoscopic demonstrations of
trichofolliculoma were published. One was defined as a “firework pattern”,
histopathologically resembling nests of cells radiating from a follicular
epithelium. The other was depicted as a “bluish nodule with a central
white-pink area, shiny white structures and dotted vessels”. This paper
presents a new dermoscopic pattern, termed “rosary bead with tassel”. The
nodule resembled a “rosary bead” and the tufted hairs, the “tassel”.  In two cases presented herein, the lesions
were in late stages with one and three-year histories. Describing a new
dermoscopic variant of trichofolliculoma related to different clinical features
can help to improve the success of the diagnosis with dermoscopy
