BACKGROUND: Mycetomas are frequent subcutaneous mycoses with typical clinical characteristics such as sinuses, blood-stained, serous, or purulent exudates as well as local swelling. Even though the most commonly affected areas are the lower limbs, we report four cases affecting the neck and midback regions, of which three were young females. We draw attention to the importance of early identification of these cases for prevention and specific treatment in order to avoid severe consequences or irreversible complications such as quadriplegia...

Mycetoma is a chronic infection, characterised by severe disability and discomfort to patients. This condition is common throughout tropical regions of the world. The Indian subcontinent and north-east Africa, especially Sudan, bear the majority of the disease burden. Due to the limited resources and isolation of these areas, the condition is usually misdiagnosed or incorrectly managed. The World Health Organisation listed the condition as a "neglected disease" in 2013. The creation of the Mycetoma Research Centre (MRC) by the University of Khartoum in 1991 has greatly contributed to the current understanding of this disabling condition...

Mycetoma is a unique neglected tropical disease caused by a substantial number of microorganisms of fungal or bacterial origins. Identification of the causative organism and the disease extension are the first steps in the management of the affected patients and predicting disease treatment outcome and prognosis. Different laboratory-based diagnostic tools and techniques were developed over the years to determine and identify the causative agents. These include direct microscopy and cytological, histopathological, and immunohistochemical techniques in addition to the classical grain culture...

Mycetoma is a localized chronic, suppurative, and deforming granulomatous infection seen in tropical and subtropical areas. It is a disorder of subcutaneous tissue, skin and bones, mainly of feet, characterized by a triad of localized swelling, underlying sinus tracts, and production of grains or granules. Etiological classification divides it into eumycetoma caused by fungus, and actinomycetoma caused by bacteria. Since the treatment of these two etiologies is entirely different, a definite diagnosis after histopathological and microbiological examination is mandatory, though difficult...

Mycetoma is a chronic granulomatous disease, classified into eumycetoma caused by fungi and actinomycetoma due to aerobic filamentous actinomycetes. Mycetoma can be found in geographic areas near the Tropic of Cancer. Mexico is one of the countries in which actinomycetoma is endemic. We report an extraordinary case of an adult male with double eumycetoma caused by Madurella mycetomatis and Fusarium verticillioides on both feet.

Fungi often infect mammalian hosts via the respiratory route, but traumatic transcutaneous implantation is also an important source of infections. Environmental exposure to spores of pathogenic fungi can result in subclinical and unrecognised syndromes, allergic manifestations, and even overt disease. After traumatic cutaneous inoculation, several fungi can cause neglected mycoses such as sporotrichosis, chromoblastomycosis, mycetoma, entomophthoramycosis, and lacaziosis. Most of these diseases have a subacute to chronic course and they can become recalcitrant to therapy and lead to physical disabilities, including inability to work, physical deformities, and amputations...

BACKGROUND: Mycetoma is a chronic, proliferative lesion of cutaneous/subcutaneous tissue characterized by draining tracts and granules in the discharge caused by actinomycetes (actinomycetoma) or filamentous fungi (eumycotic mycetoma). OBJECTIVES: This case report describes the unusual finding of a cutaneous mycetoma of the lateral wing of the right nostril in a gelding. ANIMAL: A 16-year-old Fjord gelding with suspected pituitary pars intermedia dysfunction (PPID) was presented for evaluation of a nonpainful, firm and raised mass involving the lateral wing of the right nostril and the lip...

AbstractMycetoma is a chronic soft tissue infection caused by fungal or bacterial pathogens, and is endemic in tropical and subtropical regions. Cases in developed countries outside the mycetoma belt are rare and usually imported by immigrants. Sporadic cases have been reported in Israel. Unpublished cases in the participating medical centers are reported. In addition, a systematic review of the literature was performed. All published mycetoma cases diagnosed in Israel were included with relevant variables collected...

Stereotactic needle biopsy, a standard of care for acquiring deep-seated pathology, has limitations and risks in some situations. We present an uncommon case with basal ganglia dematiaceous mycetoma. Due to the firm consistency of the lesion, the initial stereotactic needle biopsy failed to provide a diagnosis. In a second operation, transtubular excisional biopsy was successfully performed to remove the entire mycetoma. We reviewed recent case series of transtubular approaches to deep-seated brain lesions and suggest this method could be a rescue for a non-diagnostic stereotactic needle biopsy and even may be the approach of choice in some cases...

The objective of the present study was the analysis of the health status of 20 patients presenting with histologically verified paranasal sinuses mycetomas (fungus balls) with special reference to CT-semiotics characteristic of the fungal ball as early as during the pre-verification period. The surgical strategy for the management of this condition has been substantiated. It is concluded that the final verification of the pathological process in question is possible only based on the results of the histological studies...

INTRODUCTION: Mycetoma is a chronic granulomatous infection. It is caused by actinomycetes or fungi. It is common in tropical countries and males. Predisposing conditions include malnutrition, poor hygiene, history of trauma, wounds on barefeet, and systemic infections. Eumycotic mycetoma commonly involves lower extremities whereas actinomycosis affects the cervicofacial, thoracic, and abdominal regions. Mycetoma presents with a chronic indurated ulcerated plague with swelling and yellowish discharge of sulfur granules...

Fungi must meet four criteria to infect humans: growth at human body temperatures, circumvention or penetration of surface barriers, lysis and absorption of tissue, and resistance to immune defenses, including elevated body temperatures. Morphogenesis between small round, detachable cells and long, connected cells is the mechanism by which fungi solve problems of locomotion around or through host barriers. Secretion of lytic enzymes, and uptake systems for the released nutrients, are necessary if a fungus is to nutritionally utilize human tissue...

Eumycetoma, a chronic fungal infection endemic in India, Indonesia, and parts of Africa and South and Central America, follows traumatic implantation of saprophytic fungi and frequently requires radical surgery or amputation in the absence of appropriate treatment. Fungal species that can cause black-grain mycetomas include Madurella spp., Falciformispora spp., Trematosphaeria grisea, Nigrograna mackinnonii, Pseudochaetosphaeronema larense, Medicopsis romeroi, and Emarellia spp. Rhytidhysteron rufulum and Parathyridaria percutanea cause similar subcutaneous infections, but these infections lack the draining sinuses and fungal grains characteristic of eumycetoma...

A 76-year-old male non-smoker presented to our institution with cough and haemoptysis. He had been treated for cavitatory pulmonary Mycobacterium tuberculosis of the right upper lobe 10 years previously. Chest radiograph and subsequent computed tomography (CT) of the chest demonstrated a right upper cavity containing a mass suspicious for mycetoma. Flexible bronchoscopy under conscious sedation demonstrated a mass obstructing the anterior segment of the right upper lobe. The abnormality was subsequently removed using a flexible endobronchial cryoprobe...

BACKGROUND: Mycetoma are rare cutaneous affections caused by pathogens such as fungi or bacteria. They settle preferentially on limb extremities. We are going to talk about an original case of mycetoma in a young Cameroonian trader. OBSERVATION: A cutaneous mass with multiple draining sinuses was received at the anatomy and cytopathology laboratory. That mass was from a 30-year-old male trader, with no particular medical history and living in Yaounde, who was received for a lesion at the sole of the foot, which appeared some months before...

Understanding deep cutaneous fungal infection requires not only reading many case reports and checking the typical clinical images of skin lesions, but also managing the patients properly to prevent misdiagnosis. Herein, I review my recent experiences with eight typical cases of deep cutaneous infections (including protothecosis and nocardiosis) in Japan. It is very important to do the four management processes; namely, KOH direct microscopic examination, skin biopsy, fungal culture, and microscopic examination of the histopathological specimen of PAS and Grocott staining...

Among the dermatological wax collections across Europe, one of the latest created is the collection from Cluj-Napoca University, Romania. The initiator was Professor Coriolan Tataru and the moulage artist employed was Dr. Richard Hoffmann. Between the years 1923 and 1928, around 200 wax moulages were made, all realised after patients hospitalised in the clinic. The majority of cases represent the dermatological infectious pathology of that time: syphilis, cutaneous tuberculosis and mycetomas. Other interesting moulages represent genodermatoses, pelagra, different cutaneous cancers, and atypical aspects of common diseases like psoriasis and eczemas...

BACKGROUND: Scedosporium apiospermum is an emerging opportunistic filamentous fungus, which is notorious for its high levels of antifungal-resistance. It is able to cause localized cutaneous or subcutaneous infections in both immunocompromised and immunocompetent persons, pulmonary infections in patients with predisposing pulmonary diseases and invasive mycoses in immunocompromised patients. Subcutaneous infections caused by this fungus frequently show chronic mycetomatous manifestation...
