Summary
A rare fungal infection caused by Cladosporium species led to hair loss in a child. Treatment with itraconazole successfully resolved the scalp infection and promoted hair regrowth.
Area of Science:
- Dermatology
- Mycology
- Pediatrics
Background:
- Scalp infections can cause hair loss and pruritus.
- Dermatophytosis and tinea capitis are common fungal scalp infections in children.
- Accurate diagnosis is crucial for effective treatment.
Observation:
- An 11-year-old girl presented with a 3-year history of hair loss and pruritus, initially misdiagnosed as trichotillomania.
- Dermoscopy revealed broken hair shafts and pinpoint black dots at the hair bases.
- Potassium hydroxide (KOH) preparation showed pigmented yeast and brown septate hyphae, consistent with fungal elements.
Findings:
- Fungal culture identified Cladosporium species, a rare cause of scalp infection.
- Microscopic examination revealed characteristic conidia and hyphae.
- The patient was successfully treated with oral itraconazole for 2 months.
Implications:
- This case highlights Cladosporium as a potential cause of pediatric alopecia.
- Dermoscopy and KOH preparations are valuable diagnostic tools for scalp infections.
- Prompt and accurate diagnosis and treatment can lead to complete hair regrowth.

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.

01:29Staphylococcal 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...
01:15Antifungal Agents
Amphotericin B is a broad-spectrum antifungal agent that exploits structural differences between fungal and mammalian cell membranes. Its amphipathic structure—featuring a hydrophobic polyene-lactone ring and a hydrophilic region containing mycosamine and carboxylic acid groups—enables selective binding to ergosterol, a sterol predominantly found in fungal plasma membranes. This selective interaction underlies the drug’s antifungal activity, although weak binding to cholesterol contributes to...
01:27Diversity of Protists II
Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...
01:27Acne 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...
01:28Fungal Phylum Ascomycota
Phylum Ascomycota, a major division within the subkingdom Dikarya, comprises a diverse range of fungal species, including both unicellular yeasts and filamentous molds such as Aspergillus and Penicillium. These fungi thrive in a variety of habitats, from aquatic ecosystems to terrestrial environments, playing crucial ecological and economic roles.Morphology and ReproductionThe defining characteristic of Ascomycetes, commonly referred to as sac fungi, is the ascus—a sac-like structure that...
