[Plicate pachyderma of the head].
The authors describe a combination of two rare hereditary dermatoses, wrinkled pachyderma of the head (wrinkled skin of the head) and neurofibromatosis. The triad of clinical symptoms: wrinkled skin of the head, acromegaly, and drumstick symptom permit the diagnosis of pachydermoperiostosis (Touraine-Solente-Golé's syndrome).
