On mucoepidermoid tumors of different sites

Muco‐epidermoid Carcinoma of the Penis

“…In addition there was 1 in the lung and 1 in the larynx. We are of the same opinion as Hamperl and Hellweg (1957) who have concluded that muco-epidermoid carcinomas occur as a manifestation of a 2-fold differentiation potentiality of columnar cells into epidermoid and mucous cells.…”

“…Muco-epidermoid tumour primarily occurs in the salivary gland and was recognised as a separate entity by Stewart et al (1945). The other reported uncommon sites are lung (Kreyberg, Liebow and Uehlinger, 1967), cervix (Hamperl and Hellweg, 1957), nasal mucosa and larynx (Ringertz, 1938), anus (Kay, 1954) and oesophagus (Weitzner, 1970). We have reported up till 1968, 10 cases of muco-epidermoid carcinoma of the salivary glands (Shrikhande and Sirsat, 1970).…”

Mucoepidermoid/Adenosquamous Carcinoma of the Skin: Presentation of Two Cases

“…This correlates with adenocarcinomas of the skin staining positive for carcinoembryonic antigen (CEA), keratin, and mucicarmine, which is eliminated with sialidase, but not hyaluronidase (epithelial sialomucin) 14 . Squamous cell carcinoma is routinely negative for intracellular epithelial mucin 14,17 . The mucin of basal cell carcinomas is eliminated by hyaluronidase digestion 14…”

Muco-epidermoid tumours of the anal canal

“…The fact that some of them have retained an ability to secrete mucin is only a reflection of the nature of the primordial tissue. It is believed that a similar histogenesis from a comparable squamo-glandular junction accounts for the presence of muco-epidermoid tumours in the cervical canal (Hamperl and Hellweg, 1957).…”

“…Since Stewart, Foote, and Becker (1945) described muco-epidermoid tumours of the salivary glands growths with a similar histological structure have been described in the oral cavity (Smith, Broadbent, and Zavaleta, 1954), uterine cervix (Hellweg, 1957), urinary bladder (Feyrter, 1956), oesophagus (Azzopardi and Menzies, 1962), and anal canal (Kay, 1954). Berg, Lone, and Stearns (1960) found reports of four cases of muco-epidermoid carcinoma of the anal canal in the literature and added a further nine cases of their own.…”
