The first syllable "pi" is pronounced with a long "i" sound as in "pie," followed by "lo" with a short "o" sound as in "lot." "Cyst" is pronounced with a long "i" sound as in "ice" and the ending "ic" is pronounced with a short "i" sound as in "sit."

Pilocystic is an adjective that is often used in the field of dermatology to describe a certain type of cystic lesion known as a pilomatrixoma. A pilomatrixoma is a benign tumor that develops in the hair follicles and usually occurs on the face or upper body. The term "pilocystic" is derived from the Latin words "pilus" meaning hair and "cysticus" meaning cyst, thereby indicating its relationship to hair follicles.
When referring to a pilocystic lesion, it signifies that the tumor is primarily composed of proliferating hair matrix cells, which are cells that produce hair. These cells form discrete cystic structures often surrounded by fibrous tissue. Pilocystic lesions are typically firm, round, mobile masses that can range in size from a few millimeters to several centimeters in diameter.
Pilocystic lesions are relatively common, particularly in younger individuals, and are usually painless. They may appear as solitary or multiple tumors and are often identified through physical examination or imaging techniques such as ultrasound or magnetic resonance imaging (MRI). In some cases, a biopsy may be necessary to confirm the diagnosis.
While pilocystic lesions are typically benign, surgical excision is often recommended to alleviate any potential symptoms or concerns regarding cosmetic appearance. Recurrence is uncommon following complete excision, but monitoring is essential due to the possibility of reoccurrence or the development of new lesions over time.
In summary, "pilocystic" refers to a cystic lesion that arises in the hair follicles, specifically indicating its relation to hair matrix cells.
