Primary Cutaneous Cryptococcosis of Nasal Ala with Extensive Tissue Destruction

Introduction/Objective Primary cutaneous cryptococcosis (PCC) is rare and shows skin lesion(s) confined to a circumscribed body region mostly in immunocompromised host, with no sign of simultaneous dissemination condition. PCC usually presents as non-specific skin lesions such as cellulitis, nodules, and ulcers, and can be misdiagnosed in biopsy. We present a case of PCC with extensive tissue destruction. Methods/Case Report A 43-year-old male, with a history of human immunodeficiency virus infection 17 years ago, presented with complaint of his nose slowly “being eaten away” over the past 5 years after a bike accident. Physical examination showed most of the left nasal ala was completely destroyed, with visualizable septum. The biopsy of the left nasal ala showed the dermis has numerous yeasts with marked variation in size and shape, in foamy stroma with little inflammation. The capsules of the yeasts were highlighted by Mucicarmine stain. Grocott methenamine silver stain showed budding yeasts. The diagnosis of cutaneous cryptococcosis, gelatinous type, was rendered. Primary cutaneous cryptococcosis was considered based on no disseminated disease found, positive serum cryptococcus antigen with low titer (1:20), the culture of the nasal lesion positive for Crptococcus Neoformans, and the history of skin injury. The patient received appropriate treatment for PCC subsequently. Results (if a Case Study enter NA) NA Conclusion We have demonstrated a very rare case of undiagnosed/untreated PCC causing extensive destruction of skin and underlying nasal tissue. Identification of the histological features of cutaneous cryptococcosis, shown in this case, is the key for making the correct diagnosis.

Cutaneous Manifestation of Disseminated Cryptococcosis Mimicking Herpes Zoster

Cutaneous cryptococcosis is classified either as localized cutaneous cryptococcosis, in which the lesions are confined to one area of the skin, or as disseminated cryptococcosis, in which cutaneous manifestations are more widespread. We report a case of fatal disseminated cryptococcosis with characteristic cutaneous manifestations. An 84-year-old woman with diabetes presented with crusted plaques and ulcers that were painful, diffuse, and erythematous to crusted and on only the left side of her face, neck, and upper chest. She was referred to our hospital from a local clinic, where herpes zoster had been suspected. She had no specific systemic symptoms. Histological examination of the skin lesion revealed granulomatous reactions and purple to reddish encapsulated spores. Cryptococcus neoformans was identified in fungal culture, and hospitalization was recommended. Oral fluconazole was prescribed, and she was admitted to another hospital. After 2 weeks, the patient's condition deteriorated, and she was transferred to our hospital. C. neoformans antigen was detected in the blood and urine during the evaluation for systemic involvement. The patient was treated with intravenous amphotericin B and fluconazole; however, she died 10 days after admission. Cutaneous manifestations of disseminated cryptococcosis can appear in various forms and mimic molluscum contagiosum, Kaposi's sarcoma, and cellulitis. In this case, the skin lesions occurred on only the left side of the face, neck, and chest, as in herpes zoster. Cutaneous cryptococcosis can occur before the onset of symptoms of systemic involvement; therefore, diagnosis is important. Systemic evaluation may reveal early markers of disseminated cryptococcosis.

First Subungual Cryptococcosis Described in an HIV Patient with Disseminated Cryptococcosis

<b><i>Background:</i></b> Cutaneous cryptococcosis occurs in 10–15% of patients with disseminated cryptococcosis. It typically presents as papulonodular molluscum-like lesions, but it can also produce a wide variety of lesions. Cryptococcal infection of the nail unit has never been reported. <b><i>Case Report:</i></b> A 28-year-old woman with a history of HIV with disseminated cryptococcosis in complete remission was referred to evaluate a subungual swelling of the right middle finger. Examination revealed an ulcero-burgeoning nodule over the right middle finger’s subungual area with onycholysis, eschar, and erosion. An excisional biopsy was performed. Histopathological analysis demonstrated multiple histiocytic granulomas centered by encapsulated yeast cells. Culture grew <i>Cryptococcus neoformans var. neoformans</i>. After 9 months of follow-up, there was no recurrence of the lesion. <b><i>Discussion:</i></b> It is the first reported case of nail involvement in the course of cutaneous cryptococcosis. Definitive diagnosis required pathology and culture. Cryptococcal infection of the nail unit was recalcitrant to systemic therapy while the remaining infection cleared. Our case report suggests that surgical excision associated with systemic therapy is the best treatment approach for subungual cryptococcosis. Recognition of rare manifestations of cutaneous cryptococcosis, such as ours, is essential because HIV cases increase continuously.

Primary Cutaneous Cryptococcosis due to Cryptococcus neoformans in an Immunocompetent Host Treated with Itraconazole and Drainage: Case Report and Review of the Literature

<i>Cryptococcus neoformans</i> is an opportunistic germ, usually causing infections in immunocompromised patients. The main sources of infection with <i>C. neoformans</i> are excrement from birds, decomposing wood, fruit, and vegetables. Primary cutaneous cryptococcosis (PCC) is a clinical entity, differing from secondary cutaneous cryptococcosis and systematic infection. We report the case of an immunocompetent 60-year-old woman with PCC due to <i>C. neoformans</i> in her right thumb. She reported an accidental injury caused by a rose thorn while she was gardening. Clinical examination showed the presence of an erythematous ulcerated nodule with elevated borders, suppuration, and central necrosis. Skin histology examination showed cutaneous and subcutaneous fibrinoid necrosis with bleeding, abscess, neutrophil-rich cellular infiltration, and the presence of PAS-, Grocott- and mucin-positive spores. The mycological culture showed milky and creamy colonies of <i>C. neoformans</i> after 3 days. As there was no previous history of pulmonary cryptococcosis, we diagnosed PPC. We treated the patient surgically with accurate debridement of nonvital tissues in the right thumb. In addition, we started itraconazole treatment 100 mg twice daily for 6 months, which led to rapid clinical improvement without relapse. PCC is a rare infection that can present with quite unspecific clinical pictures including acneiform lesions, purpura, vesicles, nodules, abscesses, ulcers, granulomas, pustules, draining sinuses, and cellulitis. Prolonged systemic antifungal therapy is necessary in order to get a healing result without relapse. We summarize all the cases of PCC in immunocompetent patients published so far in the literature.
