Skin involvement as the first manifestation of systemic aspergillosis in patients after allogeneic hematopoietic cell transplantation

Secondary cutaneous aspergillosis in a child with Behçet’s disease: a case-based update

Background

Invasive aspergillosis (IA) is one of the rarest opportunistic fungal infections and has increased in frequency worldwide in recent years. It is a life-threatening infection associated with high mortality rates. Invasive pulmonary aspergillosis (IPA) is the most severe form of the disease. Extrapulmonary forms can develop as a primary infection or occur as part of a disseminated infection from the lung in severely immunocompromised patients. The major limitation in the management of these infections is the challenge of early diagnosis.

Case presentation

Here we report a case of secondary cutaneous aspergillosis that developed from extensive pulmonary aspergillosis in a 3-year-old female who underwent immunosuppressive therapy for a diagnosed Behçet disease (BD). Aspergillus hyphae were identified on skin biopsies. Cultures grew Aspergillus fumigatus. The diagnosis of cutaneous aspergillosis enabled us to diagnose IPA, although there was no mycopathological proof of lung infection. The patient was successfully treated with voriconazole (8 mg/kg/day) and surgical debridement of the skin lesion.

Conclusions

Although cutaneous involvement in aspergillosis is extremely uncommon, it may be the presenting feature in some cases, allowing for an accurate and timely diagnosis of deeply infected sites. Accordingly, when evaluating skin lesions in immunocompromised individuals, especially debilitated children with underlying diseases requiring long-term immunosuppressive agents, cutaneous aspergillosis should be vigilantly considered.

Clinical and Epidemiological Profile of Patients with Invasive Aspergillosis from a Fourth Level Hospital in Bogota, Colombia: A Retrospective Study

Invasive aspergillosis (IA) is a severe mycosis caused by Aspergillus species. The infection mainly affects immunocompromised patients with a significant clinical burden. This study aimed to determine the clinical and epidemiological characteristics of patients diagnosed with IA in a fourth level hospital in Colombia, as these data are scarce in the country. A retrospective, observational study, from a single center was conducted with 34 male and 32 female patients, between 1 month- and 90-year-old, diagnosed with proven (18.2%), probable (74.2%) and possible (7.6%) IA, during a 21-year period. The most frequent underlying conditions for IA were chemotherapy (39.4%) and corticosteroid use (34.8%). The lung was the most common affected organ (92.4%). Computed tomography (CT) imaging findings were mainly nodules (57.6%) and consolidation (31.8%). A low positive correlation was found between serum galactomannan and hospitalization length. Aspergillus fumigatus prevailed (73.3%) in sputum and bronchoalveolar lavage cultures. Most patients were hospitalized in general wards (63.6%) and treated with voriconazole (80.3%). Mortality rate was 15.2%. Common risk factors for IA were identified in the Colombian cohort, including medications and underlying diseases. However, their frequency differs from other countries, reinforcing the idea that local surveillance is essential and at-risk patients should be carefully monitored.

Primary cutaneous aspergillosis caused by Aspergillus.fumigatus in an immunocompetent patient: A case report

RATIONALE

Primary cutaneous aspergillosis in immunocompromised patients has been well described in extensive investigations. However, in immunocompetent hosts, primary cutaneous infection of aspergillus occurs rarely, and remains poorly characterized.

PATIENT CONCERNS

We present a case of primary cutaneous aspergillosis manifested by erythematous plague covered with flava eschar.

DIAGNOSES

The patient was diagnosed with primary cutaneous aspergillosis.

INTERVENTIONS

Treatments with oral itraconazole at a dose of 75 mg/d and local wound care with ciclopirox olamine ointment were administered.

OUTCOMES

After half a month, a partial resolution and a decrease in tenderness indicated gradual improvement, and a complete remission was achieved 2 months later.

LESSONS

Primary cutaneous aspergillosis could occur in immunocompetent hosts. The initial lesions may appear in different forms, including macules, papules, nodules, or plaques. Repeated biopsy of a skin lesion for both culture and histopathology is needed.

A near fatal case of invasive aspergillosis

Background:

Invasive aspergillosis (IA) rarely presents with endobronchial nodules or pseudomembranes on bronchoscopy. We describe a case of invasive aspergillosis in a patient with systemic lupus erythematosus (SLE), in which a fungal etiology was suspected after visualization of scattered, white endobronchial nodules.

Case Report:

A 36-year-old-female with history of SLE developed cardiorespiratory shock. Bronchoscopy indicated the presence of endobronchial lesions, and serologic studies were consistent with IA. Given high index of suspicion for fungal disease in an immunocompromised host, empiric antifungals were discontinued and voriconazole initiation resulted in a successful therapy.

Conclusions:

This case highlights the importance of a high index of suspicion for fungal diseases, especially among critically ill hosts with endobronchial lesions, who develop rapid cardio-respiratory impairment. Failure to recognize endobronchial patterns of fungal infection may lead to treatment delay and adverse clinical outcomes.
