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]
Cutaneous lymphoid hyperplasia with nodular pattern, a condition of the skin characterized by a solitary or localized cluster of asymptomatic erythematous to violaceous papules or nodules [2]: 725 Cutaneous lymphoid hyperplasia with bandlike and perivascular patterns, a condition of the skin characterized by skin lesions that clinically ...
Smaller (less than 0.5 cm) raised soft tissue bumps may be termed papules. [3] The evaluation of a skin nodule includes a description of its appearance, its location, how it feels to touch and any associated symptoms which may give clues to an underlying medical condition. [4] Nodules in skin include dermatofibroma [5] and pyogenic granuloma. [6]
Prurigo nodularis (PN), also known as nodular prurigo, is a skin disorder characterized by pruritic , nodular lesions, which commonly appear on the trunk, arms and legs. [1] Patients often present with multiple excoriated nodules caused by chronic scratching.
Cutaneous lupus mucinosis, also known as papular and nodular mucinosis in lupus erythematosus, papular and nodular mucinosis of Gold, and papulonodular mucinosis in lupus erythematosus, is a cutaneous condition characterized by lesions that present as asymptomatic skin-colored, at times reddish, 0.5–2 cm papules and nodules.

A hematoxylin and eosin-stained sample of the papule or nodule can be examined under a microscope to diagnose cutaneous leiomyomas. [18]All cutaneous leiomyomas typically exhibit interlacing fascicles of spindle cells with considerable levels of eosinophilic cytoplasm and a blunt-ended, elongated, cigar-shaped nucleus with perinuclear halos on cross section when stained with hematoxylin and ...
Fibrous papules are also termed facial angiofibromas and were formerly and incorrectly termed adenoma sebaceum (fibrous papules are unrelated to sebaceous glands [4]). They develop in up to 8% of the general adult population and occur as 1 to 3 [ 5 ] pink to red, [ 4 ] dome-shaped papules in the central areas of the face, nose, and/or lips. [ 6 ]
They can be smooth and flat, or they can seem like reddish, pink, violaceous, or brown papules with a slightly elevated dome-shaped surface. [4] There have been a few cases reported with bilateral involvement and even widespread forms. [2] MCAH lesions do not seem to spontaneously remit; instead, they grow over weeks to months. [5]
