Hypertrichosis cubiti, a case report and literature review

Hypertrichosis cubiti is an uncommon congenital hypertrichosis with links to genetic syndromes, both autosomal dominant and recessive, with variable penetrance and expressivity. It may also present in sporadic cases with no phenotypic abnormalities or family history.

Multiple nevoid hypertrichosis as an isolated developmental defect

A 3-year-old girl presented with longer hair on the left side of her scalp, coarse hair of abnormal length on her extremities, and a tuft of hair in the lumbosacral region, with all hair distributed on normally pigmented skin. Neither similar or relevant family history nor associated extracutaneous abnormalities was detected after a thorough examination. Clinical diagnosis of patchy nevoid hypetrichosis was confirmed by histology. Nevoid hypertrichosis is a rare hair growth disorder that usually presents at or soon after birth. It is characterized by patches of hypertrichosis distributed in a segmental pattern. It may be accompanied by mental, ocular, or myoskeletal abnormalities. Cases of nevoid hypertrichosis with multiple patches presenting as a solitary developmental defect have been rarely described in the literature.
