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...

Accessory Structures of the Skin: Sebaceous Glands

Accessory Structures of the Skin: Sebaceous Glands

A sebaceous gland is a type of oil gland found almost all over the skin ( except palms and soles) and helps lubricate and waterproof the skin and hair. Most sebaceous glands are associated with hair follicles. They generate and excrete sebum, a mixture of lipids, onto the skin surface, thereby naturally lubricating the dry and dead layer of keratinized cells of the stratum corneum, keeping it pliable.
These glands that produce the oils on the skin and hair are holocrine glands. The mature...

Skin Diseases and Disorders

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

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...

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...

Leishmaniasis

Leishmaniasis

Leishmaniasis is a protozoal disease caused by species of the genus Leishmania and transmitted through the bite of infected female sandflies. The parasite exists in two principal morphological forms during its life cycle. A sandfly acquires intracellular amastigotes from an infected reservoir host, such as a dog. Within the sandfly, these forms differentiate into motile, flagellated promastigotes. During a subsequent blood meal, promastigotes are injected into the human host, where they...

Summary

A rare case of non-Hodgkin lymphoma presented with skin lesions that resembled seborrheic dermatitis. Early diagnosis of lymphoma is crucial as it can mimic common benign skin conditions.

Area of Science:

Dermatology
Oncology
Pathology

Background:

Non-Hodgkin lymphoma (NHL) can manifest with diverse cutaneous presentations.
Cutaneous lymphomas may initially mimic benign dermatological conditions, delaying diagnosis.

Purpose of the Study:

To report a unique case of non-Hodgkin lymphoma presenting as seborrheic dermatitis-like lesions.
To emphasize the importance of considering lymphoma in the differential diagnosis of atypical dermatoses.

Main Methods:

Case report detailing clinical presentation, diagnostic workup, and histopathological findings.
Review of relevant literature on cutaneous lymphoma mimicking benign skin conditions.

Main Results:

The patient presented with erythematous, scaling plaques characteristic of seborrheic dermatitis.
Histopathological examination confirmed the diagnosis of non-Hodgkin lymphoma.
The clinical presentation posed a diagnostic challenge due to its similarity to common dermatoses.

Conclusions:

Clinicians must maintain a high index of suspicion for non-Hodgkin lymphoma when encountering cutaneous lesions that mimic benign dermatoses.
Early recognition and diagnosis of cutaneous lymphoma are essential for timely and effective treatment.
This case highlights the importance of thorough dermatopathological evaluation for atypical skin presentations.
