This case study details a rare instance of multiple intravascular papillary endothelial hyperplasia (IPEH) lesions on the skin and bone of a 75-year-old man. Liver dysfunction may have induced these vascular growths through microthrombus formation.
Area of Science:
- Vascular pathology
- Dermatopathology
- Oncology
Background:
- Intravascular papillary endothelial hyperplasia (IPEH) is a rare benign vascular proliferation.
- Multiple IPEH lesions are exceptionally uncommon, particularly when affecting both skin and bone.
Observation:
- A 75-year-old male presented with numerous recurrent black papules across his body.
- Over three years, 20 skin lesions were surgically removed and diagnosed as IPEH.
- A similar vascular lesion was identified on the patient's tibia.
Findings:
- Histological confirmation of intravascular papillary endothelial hyperplasia (IPEH) in multiple cutaneous lesions.
- Identification of a concurrent IPEH lesion in the bone (tibia).
- The patient had a history of hepatitis C, hepatoma, and coagulopathy.
Implications:
- This case highlights the extreme rarity of disseminated IPEH involving both skin and bone.
- The findings suggest a potential link between liver dysfunction, coagulopathy, and the development of multiple IPEH lesions.
- Microthrombus formation secondary to hepatic dysfunction is proposed as the underlying mechanism.

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.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen and...
