Article Abstract
Introduction: Mycetomas are inflammatory pseudo-tumors containing fungal or actinomycosic-type grains. They are frequent in tropical and subtropical countries and unknown in Tunisia.
Patients And Methods: We conducted a retrospective study of 12 cases of mycetoma registered in the Dermatological department of the university hospital in Sousse (central Tunisia) over a period of 27 years, from 1974 to 2001. The diagnosis was confirmed by anatomopathological and/or mycological examination.
Results: The mean age at the onset was of 49 years and the sex ratio of 1. A notion of a traumatism was reported in two cases and eight patients had various agricultural activities. The mean duration of progression was of eight years. The localization was the foot in 10 cases. The mycetoma was of actinomycosic origin in 10 cases, due to Actinomadura madurae in nine cases, to Nocardia spp in one case and of fungal origin in 2 cases:Pseudoallescheria boydii in one case and Madurella mycetomi in the other. Antibiotic therapy was associated with surgical exeresis in nine cases and amputation in the other two cases.
Comments: Confrontation of our results with those of Tunisian series and a review of the literature, helped to specify the clinico-epidemiological characteristics and progression of mycetoma in Tunisia. These characteristics are: the rareness of the infection, the relative frequency of affection in women, the proximal involvement of the foot, the frequency of agricultural activity and the rareness of traumatic past history, the predominance of the actinomycosic origin due to Actinomadura madurae, and the need to associate surgical exeresis with the medical treatment or amputation in order to stop the progress of the disease.

Eumycetoma, a chronic fungal infection caused by , is a neglected tropical disease characterized by tumor-like growths that can lead to permanent disability and deformities if untreated. Predominantly affecting regions in Africa, South America, and Asia, it imposes significant physical, social, and economic burdens. Current treatments, including antifungal drugs like itraconazole, often show variable efficacy, with severe cases necessitating surgical intervention or amputation.

Background: Mycetoma is a chronic granulomatous disease affecting the skin, subcutaneous tissues, and bones, particularly in tropical and subtropical regions. Sudan, especially its Eastern Sinnar locality, experiences a significant burden due to environmental conditions and limited access to healthcare, while the population's lack of awareness and understanding often leads to delays in diagnosis and treatment.
Methods: We conducted a descriptive cross-sectional, community-based study in Eastern Sinnar, Sudan, to investigate the prevalence, risk factors, and awareness of mycetoma among local residents.

Introduction: Deep mycoses acquired by penetrating trauma to the skin can have varied and sometimes atypical morphological presentations resulting in diagnostic dilemmas and delay in treatment onset. Histopathology can be a useful tool in not only diagnosing but also differentiating various deep mycoses.
Aims And Objectives: To observe various morphological presentations and histopathological features of deep fungal infections.

Mycetoma is a granulomatous disease of subcutaneous tissue that is caused by different species of aerobic filamentous bacteria (actinomycetoma) or fungi (eumycetoma). Mycetoma treatment depends on the causative pathogen, and it mainly consists of antimicrobial interventions or surgery. Aspergillus terreus is an etiologic agent of invasive aspergillosis and a rare cause of eumycetoma that is common in central and southern China.
