Lichen spinulosus is a rare skin disorder characterized by follicular keratotic papules that are grouped into large patches. [2] It is a variant of keratosis pilaris named for its resemblance to a patch of lichen .
Keratosis pilaris (KP; also follicular keratosis, lichen pilaris, or colloquially chicken skin. [1]) is a common, autosomal-dominant, genetic condition of the skin's hair follicles characterized by the appearance of possibly itchy, small, gooseflesh-like bumps, with varying degrees of reddening or inflammation. [2]
Standard skin surface biopsy (SSSB) is a noninvasive method used for diagnosis. [ 1 ] Favre-Racouchot syndrome , eruptive vellus hair cysts , keratosis pilaris , and comedogenic acne are among the conditions that might be identified as differential diagnoses for facial trichostasis spinulosa.
Diagnosis is based on symptoms, supported by a skin biopsy or blood tests. [6] While no cure is known, treatment may improve symptoms. [2] Medications used include corticosteroids, methotrexate, and non-steroidal anti-inflammatory drugs (NSAIDs). [2] Outcome depends on the extent of disease. [3]
[19] [20] Clinically, the diagnosis of any particular skin condition is made by gathering pertinent information regarding the presenting skin lesion(s), including the location (such as arms, head, legs), symptoms (pruritus, pain), duration (acute or chronic), arrangement (solitary, generalized, annular, linear), morphology (macules, papules ...
Disseminate and recurrent infundibular folliculitis, keratosis pilaris, lichen spinulosus, trichostasis spinulosa, and trichodysplasia spinulosa are among the conditions included in the differential diagnosis of traumatic anserine folliculosis. [2]
Visual diagnosis is made by the "stuck on" appearance, horny pearls or cysts embedded in the structure. Darkly pigmented lesions can be challenging to distinguish from nodular melanomas. [ 10 ] Furthermore, thin seborrheic keratoses on facial skin can be very difficult to differentiate from lentigo maligna even with dermatoscopy .
Trichodysplasia spinulosa (also known by many other names, including viral-associated trichodysplasia spinulosa, viral-associated trichodysplasia, pilomatrix dysplasia and ciclosporin-induced folliculodystrophy, although the last is a misnomer) is a rare cutaneous condition that has been described almost exclusively in immunocompromised patients, usually organ transplant recipients, on ...
