Abstract

PURPOSE: To report a case of apocrine sudoriferous cyst in the left medial canthal region occurred after trauma.
CASE SUMMARY
A 75-year-old woman was referred for mass in the medial canthal region after trauma. The patient had got injured and been sutured on left medial canthal region when she was 11 years of age. The painless mass in the left canthal region has occurred after that. The orbital computed tomography showed a 20 x 12 x 19 mm-sized cystic mass. On physical examination, left telecanthus, left exotropia and left hypertropia were also observed. The cyst contained turbid grayish fluid and was removed completely through transcutaneous incision. On histopathologic examination, the cyst was confirmed to apocrine sudoriferous cyst lined by two-layered cuboidal epithelia.

  Figure 1. Preoperative photograph. There is an 18×17 mm-sized cystic mass (arrow). The mass is soft, movable and nontender. Telecanthus and deviated eyeball are also observed on the left side.

• 

  Figure 2. Axial (A) and coronal (B) CT scans show a 20×18×12 mm-sized cystic mass with smooth margin in medial aspect of left lower eyelid. Peripheral nodular calcifications are also observed. There is no connection between the cystic mass and the lacrimal drainage system.

• 

  Figure 3. (A),(B) The microscopic photographs show apocrine sudoriferous cysts lined by double-layered cuboidal epithelia (arrows)(H-E stain, ×40, ×400). (C), (D) Some epithelial cells contain PAS-positive, diastase-resistant granules (arrowheads) on their apical surfaces (PAS stain, ×40, ×400).
