Summary
Masson's tumor, or intravascular papillary endothelial hyperplasia (IPEH), is a rare benign vascular tumor. This case report highlights its unusual thumb presentation and emphasizes histopathological diagnosis to differentiate it from serious conditions like angiosarcoma.
Area of Science:
- Vascular Pathology
- Dermatopathology
- Surgical Oncology
Background:
- Masson's tumor, also known as intravascular papillary endothelial hyperplasia (IPEH), is a rare benign vascular neoplasm.
- Clinical presentation can mimic other soft tissue tumors, necessitating accurate diagnostic methods.
- Histopathological examination is crucial for definitive diagnosis.
Observation:
- A 67-year-old patient presented with a painful two-month-old lesion on the left thumb.
- The lesion's clinical appearance was atypical for common soft tissue tumors.
- Excisional biopsy revealed histopathological features consistent with Masson's tumor (IPEH).
Findings:
- Histopathological confirmation of Masson's tumor (IPEH) in a rare presentation on the thumb.
- The patient achieved good functional outcomes following surgical excision.
- This represents the first reported case of Masson's tumor from Kuwait.
Implications:
- Dermatologists and surgeons must be aware of Masson's tumor's unusual presentations.
- Distinguishing IPEH from potentially malignant conditions, such as angiosarcoma, is critical.
- This report aids in recognizing Masson's tumor and differentiating it from mimickers.

01:11Papillary Dermis
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...

01:29Cardiomyopathy III: Hypertrophic Cardiomyopathy
Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...
01:30Peripheral Artery Disease I: Introduction
Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...
01:21Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
01:30Venous Thrombosis I: Introduction
Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...
01:22Portal Hypertension
Portal hypertension is an increase in blood pressure within the portal venous system. Normally, this pressure is less than 5 mmHg. It is considered clinically significant when it rises above 10 mmHg. At this threshold, complications from altered blood flow and venous congestion emerge.EtiologyPortal hypertension arises from conditions that impede blood flow through the liver. The most common cause is cirrhosis, in which chronic liver injury leads to fibrotic scarring. This fibrosis narrows or...
