“…Pachydermodactyly is a clinical variant of knuckle pads, frequently observed in middle-aged adults that only affect the dorsal aspect of the fingers [9,10]. In both diseases, an association with Dupuytren or Ledderhosc contractures, carpal-tunnel syndrome and palmoplantar keratoderma has been reported [5,10].…”

Pachydermodactyly is a rare form of superficial digital fibromatosis characterized by progressive asymptomatic thickening of the back and sides of the proximal interphalangeal joints of the fingers. Atrophia maculosa varioliformis cutis is an acquired dermal atrophy, localized on the cheeks. Only a few cases of each pathology have been published. We find it interesting to report the case of a patient with both conditions as these two connective-tissue diseases are very rare. The association is probably fortuitous.

“…Occupational lichen simplex chronicus‐like lesions are well known. 43–48 Familial cases associated with Dupuytren's contracture and other fibromatous lesions may represent hereditary polyfibromatosis. 48 Quiroga and Aberastury 49 described a patient with knuckle pads and marginal hyperkeratosis of the hands (DCPH?).…”

“…Although they can be associated to repetitive local trauma (for example repetitive batting of the knuckles, e.g. by boxers or suction the fingers by children), coexist with palmar (Dupuytren's disease) or plantar fibromatosis (Ledderhose's disease) or Peyronie's disease (3–5) , most KP are idiopathic (6–8) . Some authors tried to distinguish them (dorsal cutaneous pads) from dorsal Dupuytren's nodules (9) , what usually is not possible clinically and not necessary assuming being similar findings.…”

Knuckle pads – a rare finding

Knuckle pads are rare harmless subcutaneous nodules that must be differentiated from joint disease of the proximal interphalangeal or rarely of the metacarpophalangeal joints as well as from other masses of the paraarticular tissues. We present a case of an otherwise healthy 36-year-old woman presenting with bilateral knuckle pads located at the dorsal aspect of the proximal interphalangeal joints. No predisposition to a specific musculoskeletal disorder was noted. Ultrasound revealed well-delimited subcutaneous hypoechoic masses without internal flow signals at color Doppler. Histology showed proliferation of myofibroblasts with a decrease of elastic filaments in the deep dermis. The clinical picture, the family history in addition to the histology allowed us to make the diagnosis of knuckle pads. We present the ultrasound findings of knuckle pads and discuss the differential diagnosis of a “swelling” in the dorsal region of proximal interphalangeal joints and metacarpophalangeal joints.
