| Diagnosis in short | |
|
| |
| LM | cyst lined by a bland bilayer, lack apocrine snouts |
| Site | eyelid |
|
| |
| Prognosis | benign |
| Clin. DDx | cystic basal cell carcinoma |
| Treatment | excision |
Eccrine hidrocystoma is a benign lesion of the eyelid.
It is occasionally spelled eccrine hydrocystoma.
General
- Benign.
- Eyelid lesion.
Clinical DDx:
- Cystic BCC.
Microsopic
- Cyst lined by a bland bilayer.
- Inner lining cells have:
- Small, round nuclei - usu. basal.
- Moderate pale/greyish cytoplasm.
- No apocrine snouts - flat surface.
- Outer lining cells - spindled.
- May be difficult to see.
- Inner lining cells have:
DDx:
- Apocrine hidrocystoma - have apocrine snouts; surface is not flat.
- Cystadenoma - has epithelial proliferation.

Lesion [Cyst], Left Lower Eyelid, Excision: - Benign cyst in keeping with eccrine hidrocystoma.
Micro
The sections show hair bearing skin with a cyst lined by a bland, flat, bilayered epithelium. The lining cells have moderate pale cytoplasm and small round nuclei.
The lesion is excised in the plane of section.
All uppercase
SKIN LESION, ADJACENT TO RIGHT EYELID, EXCISION: - ECCRINE HIDROCYSTOMA.
Micro
The sections show hair bearing skin with a cyst lined by a bland bilayered epithelium. The predominant lining cell has moderate pale grey cytoplasm and a small round nucleus.
The lesion is excised in the plane of section.
