Summary
This case study highlights subcutaneous sarcoidosis, a rare skin condition presenting as firm nodules. Early diagnosis and treatment with oral glucocorticoids are crucial for managing this granulomatous inflammation.
Area of Science:
- Dermatology
- Pathology
Background:
- Sarcoidosis is a multisystem inflammatory disease characterized by non-caseating granulomas.
- Cutaneous involvement is common, but subcutaneous sarcoidosis is a rare presentation.
Observation:
- A 30-year-old man presented with hypopigmented macules and erythematous papules on the lips and extremities.
- He later developed firm, non-tender, subcutaneous nodules on his limbs.
Findings:
- Clinical and histopathologic findings confirmed cutaneous and subcutaneous sarcoidosis.
- Histopathology revealed epithelioid cell tubercles within the subcutaneous fat.
- Systemic evaluation excluded extracutaneous sarcoidosis involvement.
Implications:
- Subcutaneous sarcoidosis requires exclusion of other granulomatous conditions.
- Early recognition of characteristic skin findings is essential for diagnosis.
- Oral glucocorticoids are the primary treatment modality for subcutaneous sarcoidosis.

01:30Leishmaniasis
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...
01:30Skin 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.

01:31Pulmonary Tuberculosis III
Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

01:26Rocky Mountain Spotted Fever
Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.
01:23Skin 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.

01:15Secondary Lymphoid Organs
Secondary organs, including lymph nodes, the spleen, and mucosa-associated lymphoid tissue (MALT), work harmoniously to protect us from disease and infection.
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...
