Abstract

Insights

This study found a rare co-infection of aspergillosis and hydatid cyst in two lung cases. Histopathology is crucial for diagnosing this rare co-occurrence, especially in immunocompromised patients.

Area of Science:

  • Medical Mycology
  • Parasitology
  • Pathology

Background:

  • Hydatid cyst is an endemic zoonotic disease.
  • Aspergillosis, caused by Aspergillus fungus, presents various lung pathologies.
  • The co-infection of hydatid cyst and aspergillosis is exceptionally rare.

Purpose of the Study:

  • To investigate the coexistence of aspergillosis and echinococcosis in archival materials.
  • To discuss the potential clinical significance of this rare co-infection.

Main Methods:

  • Reevaluation of 100 archival hydatid cyst cases by four pathologists.
  • Application of Grocott's methenamine-silver (GMS) and periodic acid-Schiff (PAS) stains for suspected co-infections.

Main Results:

  • Two cases of coexisting aspergillosis and hydatid cyst were identified among 100 cases.
  • Both identified cases were located in the lung and occurred in immunocompetent patients.

Conclusions:

  • The coexistence of aspergillosis and hydatid cyst warrants attention, particularly in immunocompromised individuals or with cyst rupture.
  • Radiological imaging lacks reliable data for detecting Aspergillus within hydatid cysts.
  • Histopathological examination is essential for accurate diagnosis and management planning.

Amebiasis01:28

Amebiasis

Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
Cryptococcal Meningitis01:27

Cryptococcal Meningitis

Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
Toxoplasmosis01:28

Toxoplasmosis

Toxoplasmosis, a zoonotic disease caused by the protozoan Toxoplasma gondii, poses significant public health challenges globally due to its high seroprevalence and varied clinical manifestations. As an obligate intracellular parasite, T. gondii can infect all warm-blooded vertebrates, but felids are its only definitive hosts, shedding unsporulated oocysts into the environment. Humans typically acquire the infection through ingestion of tissue cysts in undercooked meat or oocysts from...
Fungal Phylum Ascomycota01:28

Fungal 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...
