The great diversity, rarity, and complex terminology of<unk> s make their diagnosis challenging. They have been misdiagnosed as other types of skin tumors including<unk> rcinomas, basal cell carcinomas, pyogenic granulomas, skin tags, plantar warts (i.e. warts on the palms or soles), fibromas, hemangiomas, pigmented moles, seborrheic keratosis, trichilemmomas, melanomas, Kaposi sarcomas, and other adnexal tumors.<unk> s are typically diagnosed based on their clinical presentation; microscopic histopathology showing tumor tissues consisting of poroid, cuticular, and/or clear cells; and, in unclear cases, the presence of tumor cells that express a YAP1::NUTM1, YAP::MAML2, and/or WWTR1::NUTM1 fusion gene. However, these fusion genes also occur in<unk> rcinomas and cannot be use to differentiate<unk> s from their malignant counterpart.<unk> s and<unk> rcinomas are distinguished based on their clinical findings and histopathology, e.g. a higher Ki67 labeling index and aberrant expression of p53, RB, and p16 proteins are more frequent in<unk> rcinoma (see Diagnosis of porcarcinomas. Dermatoscopy, particularly when revealing a "leaf- and flower-like pattern" in a skin tumor, has been used as a strong indicator that the lesion is a<unk> , but confirmation of this diagnosis ultimately relies on histopathological analyses. There is no clear-cut evidence that diagnosing a<unk> 's variant type caries any clinical or therapeutic significance. Treatment Superficial<unk>  tumors have been treated by shaving (i.e. removal using a sharp razor) or electrosurgical destruction. Deeper lesions have been removed by excisional biopsy (i.e. a procedure in which an entire tumorous or suspicious area is removed) or simple surgical excision. Since<unk> s are almost always benign tumors and rarely recur after their removal, these treatments are in general curative.
