Background:
Glomus tumour is a rare benign hypervascular lesion mainly found in the subungual region of the fingers.
Case Presentation:
A young, right-handed female experienced episodic and increasing pain in her left thumb. The pain was triggered by cold weather and light pressure. Painkillers and non-steroid anti-inflammatory drugs gave little or no relief. She saw several doctors who suspected various diagnoses, including tennis elbow, carpal tunnel syndrome and cervicobrachialgia. None of these could be verified.
Interpretation:
The case illustrates how a rare benign tumour, that can be effectively treated, can lead to chronic disability when a correct diagnostic workup is severely delayed.

Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
