Abnormal Proliferation

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...

Toxidromes: Clinical Features

Toxidromes: Clinical Features

Toxidromes are specific patterns of symptoms resulting from toxic substance exposure. They help in the identification and treatment of poisoning. The symptoms of each toxidrome group indicate poisoning by a certain class of chemicals or drugs.1. Sympathomimetic: Stimulates the sympathetic nervous system. Symptoms include agitation, increased heart rate (HR), blood pressure (BP), respiratory rate (RR), temperature, and pupil size. Drugs like cocaine and amphetamines, along with tremors and...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Inflammatory Bowel Disease IV: Clinical Manifestations

Inflammatory Bowel Disease IV: Clinical Manifestations

Inflammatory bowel disease (IBD) encompasses two major chronic disorders—ulcerative colitis and Crohn’s disease—each characterized by relapsing episodes of gastrointestinal inflammation. Although they share certain clinical features, their patterns of involvement and manifestations differ in ways that aid diagnosis and guide management.Ulcerative ColitisUlcerative colitis is limited to the colon and rectum and involves continuous inflammation of the mucosal layer. The disease course is marked...

Skin Cancer

Skin Cancer

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Area of Science:

Dermatology
Oncology

Background:

Pilomatrixoma is a rare, benign skin neoplasm originating from hair matrix cells.
It most commonly affects children aged 5-15 years, typically presenting as a solitary, hard lesion, often on the face.

Observation:

Multiple pilomatrixomas are uncommon and can be associated with systemic syndromes like myotonic dystrophy.
This report details an exceptionally rare case of multiple, anetodermic, and rapidly growing pilomatrixomas in a 17-year-old female.

Findings:

The diagnosis is primarily clinical, supported by imaging like ultrasound.
Surgical excision remains the definitive treatment for pilomatrixoma.

Implications:

This case underscores the importance of considering atypical presentations of pilomatrixoma, even in older individuals.
Recognizing rare variants is crucial for accurate diagnosis and appropriate management of pilomatrixoma.
