“…This classification accounts for the small, rudimentary skin tags often observed on the ulnar aspect of the hand, which many authors believe represent the sequelae of pedunculated duplications that have undergone in utero autoamputation. The histopathology of these lesions is identical to that seen in residual skin tags following postnatal suture ligation [2,11,12,16].…”

We report two cases resulting in complications following suture ligation treatment for ulnar polydactyly. One case consisted of bilateral, retained gangrene and cellulitis, and a second case consisted of a residual, sensitive skin tag. The case involving gangrene and cellulitis developed after an unsuccessful suture ligation of bilateral pedunculated duplicated digits. The second case developed after suture ligature ablation of a rudimentary digit in the nursery but presented 3 years later with a residual symptomatic nubbin. Both cases were treated by surgical excision of the residual tissue in the operating room. The first case illustrates a morbid complication following unsuccessful ligature while the second case demonstrates the inevitable suboptimal long-term outcome associated with what has traditionally been considered "successful" suture ligation.

“…RP is a congenital anomaly first described in 1954 ( 1 ), which often consists of a poorly formed digit, piece of cartilage, or vestigial nail apparatus, and is considered an autosomal-dominant disorder with an unknown genetic basis ( 2 ). RP is characterized by isolated skin-coloured nodules or pedunculated cord-like structures, primarily at the ulnar side of the little finger or sometimes the radial side of the thumb ( 3 ). Rudimentary digits on the bilateral radial aspect of the thumbs are extremely rare.…”

“…Rudimentary digits on the bilateral radial aspect of the thumbs are extremely rare. Histologically, RP typically shows a marked neural proliferation in the dermis, with many Meissner corpuscles (also known as Wagner-Meissner corpuscles), which are ellipsoid mechanoreceptors that play an essential role in somatosensory acuity ( 3 , 4 ). Occasionally, abundant Merkel cells are seen in the basal layer or superficial dermis.…”
