BACKGROUND: Fine needle aspiration biopsy (FNAB) of the skin is useful in subcutaneous lesions. Dermatophytes are almost exclusively superficial cutaneous mycoses and constitute 70-80% of all mycoses and 5% of dermatologic consultations. Inflammatory and invasive forms, as well as infections that remain in chronic forms or persist in spite of treatment, are more frequent in immunocompromised individuals. The clinicalpresentations of these invasive cases are dermatopbytic granulomas (granuloma of Wilson-Majocchi and pseudomycetoma) or Hadida's disease...

The effectiveness of a simple PCR protocol performed on paraffin-embedded tissues, obtained from histopathologically and culturally diagnosed cases of dermatophytic pseudomycetoma DPM was tested. The specimens were investigated using previously described primers (DH1L and DH1R) targeting the 18S rDNA gene and amplifying a 183-bp fragment. Microsporum canis was identified from all samples. The PCR protocol described in the present work demonstrated a 100% concordant result comparing the molecular characterisation with phenotypic characterisation of dermatophytes...

A case of a dwarf hamster with two progressively growing nodules on the right fore limb is described. These were excised following ineffective medical treatment and were submitted for histopathological examination, which revealed bacterial pseudomycetoma in both nodules. To the authors' knowledge this is the first reported case of bacterial pseudomycetoma in a dwarf hamster.

We describe mycetoma caused by Microsporum canis occurring in a 9-year-old African-American girl. Pathologic evaluation showed a granulomatous dermatitis with numerous large fungal grains containing septate hyphae that were Fontana-Masson positive. Two cultures of pure grains grew M. canis. Mycetoma due to dermatophytes is very uncommon. The few instances reported have been pseudomycetoma (grains in the absence of sinus tracts). Our patient developed sinus tracts (true mycetoma). No prior reports were found of M...

Gynecomastia is the most common cause of breast enlargement in males. Trichophyton rubrum is a common dermatophyte, is responsible for a variety of infections, and may rarely manifest as a dermatophytic pseudomycetoma. We report the case of a 52-year-old man who presented with progressive bilateral breast enlargement. This is the first reported case of bilateral breast pseudomycetoma due to T. rubrum. Long-term antifungal therapy with itraconazole was successful.

Histopathological analysis demonstrates the morphology of the fungi and shows their relationship with tissue lesions, which is a valuable information in the diagnosis of veterinary mycoses, especially in superficial infections where reservoirs make difficult the diagnosis using other techniques. On the other hand, histopathological analysis should be complementary to other methods such as culture, immunohistochemistry, serology, PCR, etc. In this work, the most relevant histopathological features of some of the most common mycoses of domestic animals, some of which have zoonotic potential, are described and their differential diagnosis is discussed...

A 1-year-old spayed female Persian cat with alopecia and weight loss had numerous variably ulcerated dermal nodules. Cytologic examination of an aspirate of one of the nodules revealed pyogranulomatous inflammation along with septate hyphae and basophilic round bodies, 0.5-1.0 microm in diameter, surrounded by a thin clear halo (arthrospores). The cytologic diagnosis was dermatophytic pseudomycetoma. Histologically, there were dermal granulomas containing poorly staining, septate hyphae with bulbous spores embedded within abundant amorphous eosinophilic material (Splendore-Hoeppli reaction), and the histologic diagnosis was pseudomycetoma-associated chronic multifocal severe granulomatous dermatitis with lymphocytic perifolliculitis and furunculosis...

Two patients presenting with subcutaneous nodules, plaques, papules and ulceration caused by dermatophytes are described in this report. The first case was atopic and had used low dose systemic corticosteroids intermittently for his asthma. The second case was a poorly controlled and long-standing diabetic patient. The diagnoses were suspected after direct microscopical examinations of the discharge materials which revealed the presence of hyaline hyphae and spores, and histological examination which showed an inflammatory infiltrate with fungal elements in the dermis...

An eight-year-old neutered female Persian cat with a four-year history of relapsing skin disease, characterised by ulcerated nodules with a yellow granular discharge, was examined. A diagnosis of granulomatous dermatitis and panniculitis (pseudomycetoma) caused by Microsporum canis was made on the basis of history, clinical signs, histopathological examination of skin biopsy specimens and culture of macerated tissue. Because previous therapy, comprising repeated surgical excision and the administration of griseofulvin and itraconazole, had not been successful, terbinafine was administered for an eight-month period...

Two cases of canine dermatophytic pseudomycetoma resulting in subcutaneous nodules resembling those previously reported in Persian cats are described. Culture performed from one nodule yielded dark yellow colonies consistent with Microsporum canis. Immunohistochemistry, using rabbit anti-M. canis, demonstrated specific binding to fungal elements in paraffin sections. The specificity of the antiserum was further tested by an agar gel immunodiffusion assay using a soluble extract from a feline isolate of M. canis as antigen...

A case of dermatophytic pseudomycetoma, in a patient with a history of recurrent lesions in the scalp, for over two years, is reported. Histopathological examination of the affected tissues revealed the mycelial aggregates or pseudogranules characteristic of the disease. Cultures of fresh tissues samples detected a fungus identified as Trichophyton tonsurans. Additional examinations failed to demonstrate lesions of tinea capitis, a probable source of the deep infection. Dermatophytic pseudomycetoma is an extremely rare form of dermatophytosis, and the rarity of such cases is the motive for the present communication...

We report the first case of a scalp pseudomycetoma due to Trichophyton schoenleinii in a 15-year-old girl from Senegal. The lesion was not associated with tinea capitis. Long-term antifungal therapy with itraconazole and terbinafine was unsuccessful but a favourable outcome was obtained after surgical removal of the lesion. Between 1973 and 1999, only 12 previous cases of dermatophyte pseudomycetoma of the scalp were reported in the literature. Clinical features and therapeutic outcomes of these cases are reviewed...

Fungal infections continue to cause major complications in cancer patients. With the increasing use of aggressive chemotherapy and stem cell transplantation causing profound, prolonged depressed immunity, the risk of invasive mycoses has increased. The prognosis of these infections is poor unless they are diagnosed and treated promptly. The management of opportunistic fungal infections is characterized by a series of unresolved problems, including initial difficulties in obtaining an early diagnosis. Clinical signs indicating a definite diagnosis of fungal infection is frequently absent in cancer patients...

A 25-year-old man presented with several prominent subcutaneous masses in the occipital region of the scalp. He had a long history of tinea capitis and tinea corporis infection. Histopathology of the occipital lesions showed mycelial aggregates in the deep dermis and subcutis. Cultures of the excised material and superficial scales grew a fungus identified as Microsporum ferrugineum. We propose the term 'dermatophyte pseudomycetoma' to describe this distinctive mycosis.

A 13-year old black girl presented with an unusual scalp lesion felt to be compatible with mycotic granuloma. She had undergone surgery two years earlier for removal of three similar scalp lesions. Material excised during surgical removal of the cyst-like lesion again revealed histopathology compatible with mycotic granuloma. Surgical material cultured out pure growth of a fungus identified as Microsporum canis Bodin. Subsequent histopathological study of the infected tissue resulted in a diagnosis of dermatophytic 'mycetoma'...

Idiopathic multicentric acro-osteolysis is a complex heterogenic disease that may simulate mycetoma. A ten-year-old child has developed the condition, diagnosed as mycetoma for 7 years. Medical genetic examination of the patient helped correctly diagnose the disease. Proband's younger brother suffered from the same condition. Segregation analysis has revealed a recessive sex-linked inheritance of the disease.
