Eccrine tumours of the hand: two cases
Journal of Hand Surgery (Edinburgh, Scotland)
|February 1, 1987
Summary
Two rare eccrine sweat gland tumors, eccrine spiradenoma and chondroid syringoma, were found in the hand. These unusual hand tumors were initially misdiagnosed as sebaceous cysts before histological confirmation.
Area of Science:
- Dermatopathology
- Surgical Oncology
Background:
- Eccrine tumors originate from sweat glands and can manifest in various forms.
- While commonly found on the trunk and head, their occurrence in the hand is infrequent.
Observation:
- Two patients presented with non-tender, rounded masses on the hand, present for 8 months to 2 years.
- The masses were subcutaneous, adhered to the epidermis, but mobile on deeper tissues.
- Pre-operative diagnosis in both cases was sebaceous cyst.
Findings:
- Histological examination confirmed one tumor as eccrine spiradenoma.
- The second tumor was identified as a chondroid syringoma.
- Both eccrine tumors are rare in the hand, with typical locations being the trunk, head, and back.
Implications:
- Highlights the importance of considering rare eccrine tumors in hand mass differential diagnoses.
- Emphasizes the need for thorough histological evaluation to distinguish benign or malignant hand tumors.
- Contributes to the understanding of the anatomical distribution of sweat gland neoplasms.
