“…Radiography, ultrasonography, and MRI show soft tissue thickening but no abnormalities of the joint space or bones [ 6 ]. Histologically, PDD is characterized by orthokeratotic or parakeratotic hyperkeratosis, acanthosis, and thickening of the dermis owing to an increased amount of fibroblasts and collagen types III and V; this differs from the collagen profile of normal skin [ 8 ]. Electron microscopy has demonstrated an increased number of thin, collagen fibers [ 9 ].…”

Pachydermodactyly (PDD) is a rare and benign acquired form of digital fibromatosis, characterized by asymptomatic fusiform soft tissue hypertrophy of the lateral aspect of the proximal interphalangeal (PIP) joints of the fingers. The etiology of PDD remains unknown, but it usually affects healthy males around the age of puberty. It can be misdiagnosed as inflammatory rheumatic diseases, especially as juvenile chronic arthritis. Here, we report a case of PDD in an 18-year-old man who had progressive fusiform swelling of the PIP joint on his left middle finger. Although he had no pain or functional limitation of movement, he chose to undergo surgical resection of the lesion to obtain a conclusive diagnosis and to rectify the deformity's appearance. Histologically, the lesion was characterized by coarse fibrosis in the adipose tissue, peripheral nerve fibers, and eccrine glands; this is compatible with a diagnosis of PDD.

Background: Pachydermodactyly is a rare, benign, acquired form of digital fibromatosis. The etiology of pachydermodactyly is unknown but is believed to be due to repeated mechanical injury of the skin. We report 2 cases identified in poultry processing workers and review other conditions associated with these cutaneous findings. Observations: The 2 workers in this report were employed as a chicken catcher and a chicken hanger. On examination, both workers had marked lateral thickening of the digits, with associated pain and pruritus. The workers' skin condition developed despite the use of protective gloves, and their symptoms improved when removed from work. However, the swelling due to fibromatosis persisted. Conclusions: Similar cutaneous findings have been reported in other occupations exposing individuals to repetitive skin trauma, and many patients demonstrating a compulsive habit of hand manipulation. This supports the conclusion that pachydermodactyly in these patients reflects repeated skin trauma. Repetitive mechanical injury in the poultry processing environment can result in considerable compensatory tissue changes. Preventive measures are needed to protect workers.

Unusual unilateral presentation of pachydermodactyly: a case report

et al. 2011

Pachydermodactyly is a rare digital fibromatosis characterized by asymptomatic fusiform soft-tissue swellings of the proximal interphalangeal joints of the hands. It usually affects healthy adolescent males with a negative family history. As a rule, clinical presentation of the disease is bilateral and symmetrical enlargement of the joints. So it can be misdiagnosed with inflammatory rheumatic diseases, especially with juvenile chronic arthritis. A prompt clinical diagnosis of the disease would prevent inappropriate treatment with immunosuppressive agents or steroids and unnecessary expensive diagnostic procedures such as biopsy or magnetic resonance imaging. Once diagnosed, patients should be advised in order to avoid repetitive traumas of the hands, rubbing and cracking of the fingers, obsessive-compulsive use of computer and video games. The joint outcome is always benign. Here, we report a case of pachydermodactyly differs from the typical clinical picture of pachydermodactyly in the unilateral distribution of the lesions.

Pachydermodactyly

Abstract: Pachydermodactyly is not well recognized by rheumatologists and should be differentiated from inflammatory arthritis involving PIP joints.
