Fibroma nuchales D23.-

Lister DM et al. 1988

Rare benign connective tissue proliferation (fibrosing dermatitis), which occurs in the neck region, but also on the back (between the shoulder blades) and the upper extremity, is blurred, sometimes painful, and benign, and affects the cutis and subcutis.

Induration of skin and subcutaneous fatty tissue of varying size, firm, plate-like or nodular. Diabetes mellitus is frequently associated. The tumour tends to recur locally after excision. Metastases are not known.

Unencapsulated, cell-deficient, mesenchymal new formation from irregularly arranged collagenous fibre strands. The cells express CD34, but not actin, desmin and S-100 protein. These displace the local subcutaneous fatty tissue, which is enclosed in an islet shape. Localized lymphocytic infiltrate islets.
