Hyperkeratotic follicular papules were the sole clinical finding in 16 of 20 patients. A diagnostic delay between first symptom development and initial diagnosis was frequent (mean 42\u00a0months). The head\/neck region was concurrently affected only in two patients. Disease stage at diagnosis was IA in two patients (10%) and IB in 18 (90%). Five patients had almost complete lesion regression, whilst there was only a slight improvement, without regression in 14. Two patients developed infiltrated papules, comedones, and small cysts during follow\u2010up. Only one patient progressed to tumor stage (IIB) five\u2009years after the first diagnosis. The mean follow\u2010up was seven\u2009years (range: 12\u2010180\u00a0months).
