Which condition might indicate the presence of multiple hairs from a single follicle?

The presence of multiple hairs emerging from a single follicle is specifically referred to as "pili multigemini." This condition occurs when a single hair follicle gives rise to multiple hair shafts, highlighting a unique growth pattern that deviates from the typical structure where one follicle produces a single hair. This phenomenon can often be observed under microscopic examination or in clinical settings where hair growth is assessed.

In contrast, folliculitis is an inflammation of hair follicles usually caused by infection or irritation, and it does not characteristically involve multiple hairs from a single follicle. A steatoma, also known as an epidermoid cyst, refers to a sebaceous cyst that does not involve the hair strands themselves explicitly. Lastly, lentigines are pigmented lesions or spots on the skin due to sun exposure, with no direct association with hair follicle structure. Thus, pili multigemini is the only option concerning multiple hair growth from one follicle, making it the correct choice.
