Summary
Subcutaneous sarcoidosis can mimic infections, delaying diagnosis. A combination of skin biopsy, chest imaging, and laboratory tests aids in confirming systemic sarcoidosis, especially in atypical cases.
Area of Science:
- Immunology
- Dermatology
- Pulmonology
Background:
- Sarcoidosis is a multisystem inflammatory disease.
- Subcutaneous sarcoidosis presents a diagnostic challenge due to its mimicry of infections like cellulitis.
- Early diagnosis is crucial for effective management.
Observation:
- A patient presented with a swollen forearm and hand, initially misdiagnosed and treated as acute cellulitis.
- Skin biopsy revealed granulomatous panniculitis, prompting further investigation.
- The patient's presentation mimicked common infections, delaying definitive diagnosis.
Findings:
- Systemic sarcoidosis was confirmed through characteristic chest roentgenogram findings.
- A high CD4/CD8 T lymphocyte ratio in bronchoalveolar lavage supported the diagnosis.
- Characteristic 'panda' and 'lambda' signs on gallium-67 scintigraphy were observed.
Implications:
- Atypical subcutaneous sarcoidosis requires a high index of suspicion.
- Skin biopsy is vital for initial diagnosis of cutaneous sarcoidosis.
- Multimodality diagnostic approach including imaging and laboratory markers is essential for confirming systemic sarcoidosis when invasive procedures are not feasible.

Staphylococcal Skin Infections
Staphylococcus aureus is a Gram-positive coccus that resides harmlessly on the skin and mucous membranes of healthy individuals. When the skin barrier is breached, it can shift from a commensal to an opportunistic pathogen. This transition is facilitated by surface adhesins, such as clumping factor B and S. aureus surface protein G (SasG), which bind to structural proteins, including loricrin and cytokeratin, in the damaged epidermis. Protein A, another key factor, binds the Fc region of...
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...

Rocky 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.
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...
Chronic Inflammation: Introduction
Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...
Atypical Pneumonia
Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease include...
