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...

Papillary Dermis

Papillary 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...

Reticular Dermis

Reticular Dermis

The papillary and reticular dermis are the two layers of the dermis. They are made of connective tissue with fibers of collagen extending from one to the other, making the border between the two somewhat indistinct. The dermal papillae extending into the epidermis belong to the papillary layer, whereas the dense collagen fiber bundles below belong to the reticular layer.
Reticular Layer
Underlying the papillary layer is the much thicker reticular layer, composed of dense, irregular connective...

Acne Infection

Acne Infection

Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...

Veins of Head and Neck

Veins of Head and Neck

The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...

Veins of Thorax

Veins of Thorax

The azygos system is a crucial part of the body's circulatory system and drains most of the thorax. It comprises the azygos, hemiazygos, and accessory hemiazygos veins.
The azygos vein, positioned just right of the midline and anterior to the vertebral column, begins at the junction of the right ascending lumbar and subcostal veins, terminating in the superior vena cava. This vein drains blood from the right side of the thoracic wall, thoracic viscera, and posterior abdominal wall.
The...

Summary

This summary is machine-generated.

Multiple blue-purple nodules on a man's trunk were initially suspected to be melanoma. Dermoscopy revealed typical features of venous hemangiomas, leading to a confident diagnosis and avoiding unnecessary treatment.

Area of Science:

Dermatology
Vascular Lesions
Dermoscopy

Background:

Differentiating benign vascular lesions from malignant neoplasms is crucial in dermatological diagnosis.
Melanoma can present with varied clinical appearances, necessitating careful evaluation.
Venous hemangiomas are common benign vascular tumors that can mimic other skin conditions.

Observation:

A 61-year-old male presented with multiple dark, blue-purple nodules on his trunk, measuring up to 5mm.
Clinical examination raised suspicion for malignant melanoma.
Dermoscopic examination revealed key features: variously sized, smooth-bordered red to blue lacunae.

Findings:

The dermoscopic features observed were characteristic of multiple venous hemangiomas.
The presence of red to blue lacunae with smooth borders is a hallmark of venous hemangiomas.
The diagnosis of venous hemangiomas was considered certain based on these dermoscopic findings.

Implications:

Dermoscopy is a valuable non-invasive tool for the accurate diagnosis of vascular lesions.
Correct identification of benign lesions like venous hemangiomas prevents unnecessary patient anxiety and invasive procedures.
This case highlights the importance of dermoscopic evaluation in the differential diagnosis of pigmented and vascular skin lesions.
