Abstract:
Disseminated cryptococcosis is a serious opportunistic fungal infection caused by a yeast-encapsulated fungus of the genus Cryptococcus neoformans. It occurs most often in patients with a significant deficit of cellular immunity and preferentially affects the central nervous system. The skin and the lungs are the most commonly affected sites outside the neuro-subarachnoid location. We report the case of a patient apparently immunocompetent who had a disseminated cryptococcosis. The disease started with the multiple purplish skin lesions, large umbilicated on the face, groin, forearm and leg with progressively increasing volume. This symptomatology had evolved in the context of weight loss and poor general condition. The diagnosis was established by the presence of cryptococcal at the skin biopsy and cerebrospinal fluid. Research of immunosuppression common pathologies were negative. Treatment was initiated based on amphotericin B for 40 days. The patient's condition deteriorates onset of paraplegia and swallowing disorders causing death in an array of cachexia. This observation points out that disseminated cryptococcosis can occur in an immunocompetent patient. The skin lesions may be the first sign of the disease.
Insights
Disseminated cryptococcosis, a fungal infection, can affect immunocompetent individuals. Skin lesions may be the initial indicator of this serious opportunistic infection.
Area of Science:
- Medical Mycology
- Infectious Diseases
- Immunology
Background:
- Disseminated cryptococcosis is an opportunistic fungal infection caused by Cryptococcus neoformans.
- It typically affects individuals with compromised cellular immunity, often targeting the central nervous system.
- Skin and lungs are common extraneural sites of infection.
Observation:
- A case of disseminated cryptococcosis in an apparently immunocompetent patient is presented.
- The initial symptoms included multiple, progressively enlarging, purplish, umbilicated skin lesions on the face, groin, forearm, and leg.
- The patient also experienced weight loss and a general decline in health.
Findings:
- Diagnosis was confirmed by the presence of Cryptococcus in skin biopsy and cerebrospinal fluid samples.
- Standard tests for common immunosuppressive conditions were negative.
- Treatment with amphotericin B for 40 days was initiated.
Implications:
- This case highlights that disseminated cryptococcosis can occur in immunocompetent hosts.
- Cutaneous manifestations can serve as the primary clinical sign of the disease.
- Early recognition of skin lesions is crucial for timely diagnosis and management, even in the absence of known immunosuppression.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
