Acral nevi may occur in all ethnic groups, but are more common in dark-skinned people. The acral nevus is a benign skin lesion that can occur at any age, but is generally noticed between 10 and 30 years of age. Both children and adults may be observed with this skin lesion.
A dermatofibroma, or benign fibrous histiocytomas, is a benign nodule in the skin, typically on the legs, elbows or chest of an adult. [3] It is usually painless. [3] It usually ranges from 0.2cm to 2cm in size but larger examples have been reported. [3] It typically results from mild trauma such as an insect bite. [3]
It is a benign, small tumor located in the skin of the distal areas of the legs and, less commonly, the arm; it has occurred mostly in females. EWSR1-SMAD3-positive fibroblastic tumor was named based on the finding that its tumor cells express a EWSR1-SMAD3 fusion gene. Since its initial description in 2018, a total of 15 cases have been ...
Nodular fasciitis occurs in all age groups but most often affects those between 20–40 years old. Males and females are equally affected. NF tumors, which may be tender or painful, typically present as rapidly growing solitary lesions that reach their final size (usually 2–3 cm) within a few weeks. [10]
A benign melanocytic nevus is a cutaneous condition characterised by well-circumscribed, pigmented, round or ovoid lesions, generally measuring from 2 to 6 mm in diameter. [1] A benign melanocytic nevus may feature hair or pigmentation as well.
Knuckle pads are benign subcutaneous fibrotic nodules that are seen in the finger joints and/or the extensor area of the foot. [6] [7] [8] From a clinical perspective, these are well-defined, non-compressible, freely moveable lesions that resemble warts and primarily affect the dorsal portion of the proximal interphalangeal (PIP) and, less frequently, the metacarpophalangeal (MCP) joints.
Morton's neuroma is a benign neuroma of an intermetatarsal plantar nerve, most commonly of the second and third intermetatarsal spaces (between the second/third and third/fourth metatarsal heads; the first is of the big toe), which results in the entrapment of the affected nerve.
Since the diseased area (lesion) is not encapsulated, clinical margins are difficult to define. As such, portions of the diseased tissue may be left in the foot after surgery. Inadequate excision is the leading cause of recurrence. [2] [7] Radiotherapy has been shown to reduce the size of the nodules and reduce the pain associated with them.
