Summary
Granuloma annulare, a benign skin condition, presents as lesions on the feet in children. This case highlights the importance of accurate diagnosis and appropriate management for pediatric granuloma annulare.
Area of Science:
- Dermatology
- Pediatric Dermatology
- Cutaneous Medicine
Background:
- Granuloma annulare is a common, benign inflammatory skin condition.
- Pediatric cases often require careful evaluation due to varied presentations.
- Accurate diagnosis is crucial for effective management and to rule out other dermatoses.
Observation:
- A 12-year-old male presented with bilateral foot lesions present for over six months.
- Previous topical treatments (antifungals, corticosteroids) were ineffective.
- Oral griseofulvin was prescribed prior to dermatology referral.
Findings:
- The patient's lesions were asymptomatic, without pruritus or pain.
- Review of systems, medical history, and family history were unremarkable.
- The clinical presentation suggested granuloma annulare, necessitating further diagnostic consideration.
Implications:
- This case underscores the diagnostic challenges in pediatric granuloma annulare.
- It emphasizes the need for a thorough differential diagnosis when initial treatments fail.
- Optimal management strategies for pediatric granuloma annulare require individualized assessment.

Diabetic Foot Ulcer
Definition A diabetic foot ulcer (DFU) is a chronic, non-healing wound that develops in individuals with diabetes. It typically occurs on pressure-bearing areas such as the heel, metatarsal heads, or hallux, and carries a high risk of infection and amputation.Pathophysiology • The development of DFUs can be explained by four interconnected mechanisms: neuropathy, ischemia, infection, and impaired wound healing. • Neuropathy is the most common factor. Sensory neuropathy reduces pain perception,...
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...

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...
Endocarditis II: Clinical Features of Infective Endocarditis
Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...
Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
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.
