A series of 36 patients having cutaneous metastases, including 32 necropsied cases in necropsy series of approximately 2,300 cases of internal carcinoma derived from the Long Beach Veterans Administration Hospital. The lung was the primary site in 17 of the 36 cases, the gastro‐intestinal tract in 8 and the genito‐urinary tract in 10; the primary site of one was uncertain. The tumors of the lung most commonly metastasized to the skin of the chest and those of the gastro‐intestinal tract and genitourinary tract to the abdominal wall. The skin metastases were multiple except for 4 cases, usually widespread in location and occasionally appeared in small crops. The tumors were most commonly solid painless elevated nodules, ranging from one to 3 cm in diameter, having an intact overlying epidermis. The microscopic appearance had features of adenocarcinoma in 26 of the 36 cases. The skin tumors were indicative of progression of the primary tumor and early fatal termination, the duration of life averaging about 3 months after the appearance of the skin tumors. The necropsies revealed widespread metastases.

The rare lesion of epithelioma cuniculatum pedis may be recognized by the gross appearance of a slow-growing, bulky, "squashy," non-healing, exophytic mass of long duration on the sole, exuding foul-smelling purulent keratin debris from numerous sinuses, and biopsies showing extensive infiltrating plaques of keratinizing, well-formed, squamous epithelium forming walls for numerous sinuses filled with purulent material. The rarity of the lesion, the slow growth, and biopsies showing relatively benign-appearing well-differentiated squamous epithelium caused considerable diagnostic difficulty to clinicians and pathologists. The tumor failed to heal, extensively penetrated the soft tissues, ultimately destroyed the metatarsal bones, and invaded the skin of the dorsum of the fott. The lesion should be treated as a slow-growing, well-differentiated squamous cell carcinoma by wide local excision or by amputation when extensive growth causes deformity of the foot or penetration of the metatarsal bones.

Dermal‐type cylindromas of parotid glands in a patient with turban tumor, and various adnexal tumors, represent a rare diathesis, apparently not reported previously. A Caucasian man, born in 1916, had a scalpectomy for turban tumor in 1957. In 1957, 1960, and 1974, dermal type cylindromas were excised from portions of both parotid glands, developing from intercalated and striated ducts; they were considered benign, based on long term followup. Adnexal tumors included multiple dermal cylindromas, trichoepitheliomas, eccrine spiradenomas, and Bowen's disease, and occurred on almost all skin surfaces. In November, 1976, a portion of a right parotidectomy included a 3.5 × 3‐cm malignant tumor having the characteristics of an invasive poorly differentiated spindle cell epidermoid carcinoma, which showed no evidence of originating from a malignant basal cell tumor. Several encapsulated and developing benign basal cell tumors were included in the specimen. Dermal‐type cylindromas of the parotid gland are considered to be a variant of basal cell adenoma, or monomorphic adenoma, basal cell type, since they consist of similar cell components, although of somewhat different arrangement and with prominent focal deposition of hyaline. Dermal‐type cylindromas should be excised conservatively as they appear. They must be differentiated from adenoid cystic carcinoma, which is an infiltrating neoplasm and requires a radical surgical approach.
