What is a Cylindroma?
Cylindromas are appendage tumors previously thought to be of apocrine differentiation. While phenotypic features differ between cylindromas and spiradenomas, recent studies have shown immunohistological and cytomorphological overlap, with both tumors exhibiting apocrine, eccrine, secretory, and ductal features.
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.
How is Cylindroma treated?
For solitary lesions, the treatment of choice is surgical excision. Other treatments include electrodesiccation/curettage and cryotherapy. For small cylindromas, the carbon dioxide laser may be used. Retamar et al used carbon dioxide laser to treat facial trichoepitheliomas in two patients, with good results.
What is dermal Cylindroma?
Dermal cylindroma is a benign neoplasm of the eccrine sweat glands, which presents in the head and neck area in majority of cases. In its most florid presentation, the entire scalp can be involved, leading to the descriptive label turban tumor.
Can adenoid cystic carcinoma come back?
A late recurrence of AdCC is common and can occur many years after initial treatment. A recurrence is cancer that has come back after treatment. A recurrence is most commonly diagnosed at the metastatic stage, meaning it has spread to other parts of the body.
Does adenoid cystic carcinoma always spread?
This form of cancer may have a tendency to recur later at the site where it first developed (local recurrence) and in approximately 50% of patients, ACC spreads to distant bodily sites, particularly the lungs (metastatic disease), potentially resulting in life-threatening complications.
How many people get adenoid cystic carcinoma?
AdCC is an uncommon type of cancer. Each year, about 1,300 people are diagnosed with AdCC in the United States. About 60% are women. AdCC can occur in adults and children.
