Dowling-Degos disease, hidradenitis suppurativa, and multiple keratoacanthomas
Considerations on the performance of immunohistochemistry for mismatch repair gene proteins in cases of sebaceous neoplasms and keratoacanthomas
with reference to Muir-Torre syndrome.
In other studies, MCPyV DNA was detected in 13% of squamous cell carcinomas and only in 1 keratoacanthoma
of 156 non-melanoma skin cancers (4,6).
the cutaneous neoplasms that are characteristic of the syndrome include sebaceous adenomas, sebaceous carcinomas, and sebaceomas, in addition to multiple keratoacanthomas
Lesions that can mimic the nail streaks of subungual melanoma include benign melanocytic nevi and nonmelanocytic tumors such as keratoacanthomas
In addition to seborrheic keratoses, benign tumors of the auricle include senile keratoses, papillomas, keratoacanthomas
, adenomas, and vascular tumors.
Supplementing with essential fatty acids (found in oils such as corn and safflower) may be useful in the case of keratoacanthomas
, but again consult your vet as to dosage and frequency of administration.
(KAs) most commonly affect people between the ages of 50 and 69 years old, although there have been reports in all age groups, including children.
Cutaneous nodules are found in many other disorders, including Gardner syndrome, Cowden syndrome, multiple trichoepitheliomas, (32) basal cell nevus syndrome, (33) multiple keratoacanthomas
, (34) and tuberous sclerosis (35) (Table).
Muir-Torre Syndrome: Muir-Torre syndrome (MTS) is defined by the development of internal malignancy, most commonly colon cancer, in association with sebaceous adenomas and epitheliomas, sebaceous carcinomas and multiple or early-onset keratoacanthomas
Synchronous appearance of keratoacanthomas
in burn scar and skin graft donor site shortly after injury.
Farro P, Zalaudek I, Ferrara G, Fulgione E, Cicale L, Petrillo G, Zanchini R, Ruocco E, Argenziano G: Unusual association between acrokeratosis verruciformis of Hopf and multiple keratoacanthomas
mainly develop on the face (lower lip, cheek, nose, and eyelid), neck, and hands.
(KAs) sometimes occur over scar sites, as did this lesion.
