Benign (nonmelanotic) epidermal tumors or tumor-like
lesions: acquired digital fibrokeratoma clear cell papulosis cutaneous horn fibroepithelial polyp hair follicle nevus large cell acanthoma melanoacanthoma pseudoepitheliomatous hyperplasia seborrheic keratosis verruca vulgaris verrucous hyperplasia
Cysts: apocrine cystadenoma apocrine hidrocystoma bronchogenic cyst cystadenoma dermoid cyst keratinous cyst pigmented follicular cyst steatocystoma vellous hair cyst
Adnexal tumors: general
• apocrine
glands: general apocrine mixed tumor apocrine tubular adenoma hidradenoma papilliferum
• eccrine sweat glands: acrosyringeal adenomatosis aggressive digital papillary adenoma chondroid syringoma clear cell acanthoma cutaneous lymphadenoma eccrine acrospiroma eccrine cylindroma eccrine poroma eccrine spiradenoma intraepidermal epithelioma microcystic adnexal carcinoma mucinous carcinoma myoepithelioma myoepithelial carcinoma papillary eccrine adenoma sweat gland carcinoma syringocystadenoma papilliferum syringoma / syringomatous carcinoma
• hair
follicles: folliculofibroma inverted follicular keratosis keratinous cyst keratoacanthoma pilar tumor pilomatrixoma trichilemmoma trichoepithelioma trichofolliculoma warty dyskeratoma
• sebaceous
glands: senile sebaceous hyperplasia nevus sebaceus of Jadassohn sebaceous adenoma sebaceous carcinoma
Premalignant / in situ: carcinoma in situ-general actinic keratosis bowenoid papulosis Bowen’s disease Paget’s disease
Carcinoma (non adnexal): adenoid cystic carcinoma adenoid squamous cell adenosquamous basal cell lymphoepithelioma-like Merkel cell Merkel-staging metastatic mucoepidermoid small cell spindle squamous cell squamous cell verrucous carcinoma staging
