Cutaneous horn has been noticed on top of many clinical conditions like keratoacanthoma
, actinic keratosis, wart, molluscum contagiosum, seborrheic keratosis, basal cell carcinoma, squamous cell carcinoma.
A 38-case retrospective study and literature review concluded that intralesional MTX is a beneficial nonsurgical treatment option for keratoacanthoma

, actinic keratosis, xanthoma, nevi, Bowen's disease, tumor invasion, and metastasis.
Melanocytic nevus was the leading diagnose among benign tumors (10 patients) that was followed by keratoacanthoma
(4) Clinically, PMA is characterized by an indolent course of a slow growing tan, gray to reddish in color, painless papillomatous, nodular or pedunculated lesion, and is often misdiagnosed as a simple cyst, chalazion, nevus or keratoacanthoma
. At times, the tumor presents with ulceration, encrustation and brownish discoloration, which leads to an overt clinical diagnosis of melanoma, basal cell carcinoma or squamous cell carcinoma.
