Why adenoid cystic carcinoma is called Cylindroma?
Adenoid cystic carcinoma was first described by Billroth in 1859 and called “cylindroma” due to its characteristic histologic appearance1. In 1953, Foote and Frazell2 renamed the lesion as adenoid cystic carcinoma.
What is adenoid cystic carcinoma prognosis?
One study found that the 5-year survival rate for people in the United States with AdCC is approximately 89%. The 15-year survival rate for people with AdCC is approximately 40%. A late recurrence of AdCC is common and can occur many years after initial treatment.
What type of doctor treats adenoid cystic carcinoma?
Surgical oncologist: a doctor who specializes in treating cancer using surgery. Maxillofacial prosthodontist: a specialist who performs restorative surgery in the head and neck areas. Otolaryngologist: a doctor who specializes in the ear, nose, and throat.
How is an adenoid biopsy done?
Under local anesthesia, he gently places a small endoscope into the nostril and then uses a tiny instrument to remove a sample of tissue from the adenoids, which are located at the back of the nose. The tissue is sent to the lab and evaluated. Results are reviewed at a follow up appointment in about a week.
What is a Turban tumor?
Cylindromas are appendage tumors of uncertain histogenesis. They may occur as solitary or multiple lesions. In case of multiple lesions numerous small papules and/or large dome-shaped nodules are present on the scalp like a turban, hence the name turban tumor.

Why is adenoid cystic carcinoma called Cylindroma?
What is the pathophysiology of adenoid cystic carcinoma (AC)?
In primary cutaneous adenoid cystic carcinoma, the tumour involves the dermis and may invade the subcutis (figure 1). The tumour is composed of basaloid cells arranged in a ductal or cribriform pattern. Characteristically there are eosinophilic hyaline membranes lining the pseudolumina within the tumour (figure 2, arrows).
What is adenoid cystic carcinoma of the breast?
Primary cutaneous adenoid cystic carcinoma and adenoid cystic carcinoma of the breast are rare but well recognized. In primary cutaneous adenoid cystic carcinoma, the tumour involves the dermis and may invade the subcutis (figure 1). The tumour is composed of basaloid cells arranged in a ductal or cribriform pattern.
What is adenoid cystic carcinoma with pseudocapsule?
Adenoid cystic carcinoma: Circumscribed tumor (left) with pseudocapsule and adjacent salivary gland parenchyma (H&E,X50) Adenoid cystic carcinoma: Tumor cells arranged in cribriform pattern with perineural invasion (centre) (H&E,X100)
Is adenoid cystic carcinoma contagious?
Adenoid Cystic carcinoma: Cyst like spaces containing eosinophilic hyalinized basal lamina material which is contagious with the connective tissue stroma of tumor (H&E,X100) Adenoid Cystic carcinoma: Cyst like spaces containing eosinophilic hyalinized basal lamina material which is contagious with the connective tissue stroma of tumor (H&E,X100)
