An 86-year-old man had a tumor in the right posterior cervical region. The lesion showed histopathologic features of pilomatricoma but differed from that lesion by the presence of cytologically atypical cells and focal squamoid differentiation. The term "malignant pilomatricoma" is suggested for this tumor.
Acrokeratoelastoidosis is a very rare entity of unknown etiology, characterized by small, firm, yellowish, translucent papules which usually appear on the margins of the hands and feet between the junction of the dorsal and palmar/plantar skin. Histologically, the most characteristic features are hyperkeratosis, mild acanthosis, and, most strikingly, fragmentation of coarse elastic fibers within the reticular dermis. This eruption is variable in terms of its onset, may be sporadic or familial, is generally asymptomatic, and has a prolonged course.

The Persian cloth shoe (Maleki) which has been in use for more than 800 years has a strong cloth sole and a woven cotton upper. In the last 20 years, used car tires have become readily available in Iran and the soles of some shoes are now made from these. A man with the typical picture of rubber dermatitis on the soles of his feet is described. On patch testing he gave a 2+ positive to PPD rubber and this was thought to be due to the fact that he had worn Maleki shoes for several years.
