That Bump Above the Eye Had a Name
A small lump near the eye may look harmless, but its location and biological behavior still need careful evaluation.
This dog was brought to AVCI because of a noticeable skin mass above the eye. Initial assessment included measuring the growth, evaluating its attachment to surrounding tissues, and performing microscopic examination of collected cells. The findings were consistent with a trichoblastoma, a skin tumor arising from primitive hair follicle cells.
Trichoblastomas are generally considered benign and typically grow slowly. However, they may continue to enlarge, become irritated or ulcerated, interfere with normal eyelid movement, or place pressure on nearby structures. Masses located around the eye require additional care because the surgical area contains limited skin and is close to the eyelids, tear structures, nerves, and the globe itself.
Management of this case involved:
• Clinical examination and measurement of the mass
• Microscopic evaluation to help characterize the lesion
• Surgical planning based on its periocular location
• Complete removal of the visible mass with appropriate tissue handling
• Postoperative pain management and incision monitoring
The mass was successfully excised, and the patient remained stable during recovery, with progressive healing of the surgical site.
Although microscopic cell evaluation can provide valuable information, definitive identification of many skin tumors is best achieved through histopathologic examination of the removed tissue. This can help confirm the tumor type, evaluate its characteristics, and assess whether the surgical margins are free of abnormal cells.
Not every lump is dangerous, but appearance alone cannot reliably determine what it is. Masses that are growing, changing, bleeding, irritated, or located near sensitive areas such as the eyes, mouth, paws, or genital region should be assessed promptly.
