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.
Inflammatory papillary hyperplasia (IPH) is a benign lesion of the oral mucosa which is characterized by the growth of one or more nodular lesions, measuring about 2mm or less. [4] [5] The lesion almost exclusively involves the hard palate, and in rare instances, it also has been seen on the mandible. The lesion is mostly asymptomatic and color ...
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]
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 ...
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 ...
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. [1] [2]
Palpable purpura is characterized by firm, elevated hemorrhagic plaques or papules that can measure several centimeters in diameter. These are typically found on dependent surfaces, like the back of a recumbent patient or the lower legs. The center of a lesion may become ulcerative, pustular, vesicular, necrotic, or nodular.
papules or nodules which are red, globular and non-blanching, with a vascular appearance; purplish nodules sufficiently similar to Kaposi's sarcoma that a biopsy may be required to verify which of the two it is; a purplish lichenoid plaque; a subcutaneous nodule which may have ulceration, similar to a bacterial abscess
