Angiolymphoid hyperplasia with eosinophilia (also known as: [1] "Epithelioid hemangioma," "Histiocytoid hemangioma," "Inflammatory angiomatous nodule," "Intravenous atypical vascular proliferation," "Papular angioplasia," "Inflammatory arteriovenous hemangioma," and "Pseudopyogenic granuloma") usually presents with pink to red-brown, dome-shaped, dermal papules or nodules of the head or neck ...
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]
Folliculosebaceous cystic hamartomas frequently manifests as a flesh-colored papule or nodule that is asymptomatic. Folliculosebaceous cystic hamartomas are usually found on the scalp or central face. [4] The lesions are usually 0.5–1.5 cm flesh-colored, exophytic, solitary, rubbery or firm, and partially umbilicated. [5]
Dissecting cellulitis of the scalp, also known as dissecting folliculitis, perifolliculitis capitis abscedens et suffodiens of Hoffman, perifolliculitis abscedens et suffodiens, or folliculitis abscedens et suffodiens, is an inflammatory condition of the scalp that can lead to scarring alopecia, which begins with deep inflammatory nodules, primarily over occiput, that progresses to coalescing ...
[2] [3] These neoplasms are relatively uncommon and typically occur on the scalp, face, and upper extremities. Clinically, pilomatricomas present as a subcutaneous nodule or cyst with unremarkable overlying epidermis that can range in size from 0.5 to 3.0 cm, but the largest reported case was 24 cm. [4]
The tumors, which are typically found in regions like the scalp with a high density of hair follicles, can be solid or solid cystic. Proliferating trichilemmal cyst frequently manifests clinically as a subcutaneous nodule that gradually grows into a big nodular mass.
Cutaneous myxoma appears as a little, slowly expanding dermal or subcutaneous lump that typically affects adults' heads and necks. [3] Alopecic lesions have been reported, [4] [5] characterized by hair tufts overlaying the lesion or even hypertrichosis. [6]
The scalp, ears, back, face, and upper arm, are common sites of sebaceous cysts, though they may occur anywhere on the body except the palms of the hands and soles of the feet. [4] They are more common in hairier areas, where in cases of long duration they could result in hair loss on the skin surface immediately above the cyst. They are smooth ...
