Pseudomycetoma for microsporum canis: report of a case diagnosed by fine needle aspiration biopsy.

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.

Paraffinomas of the facial area: treatment with systemic and intralesional steroids.

We present a case of a 32-year-old male patient with a history HIV infection, who administered vitamin E and almond oil into the malar region and chin. On histology the main pathological finding was a foreign body granulomatous reaction. The patient was treated with 20-mg prednisone and intralesional triamcinalone.

Primary cutaneous coccidiodomycosis: case report and review of the literature.

Background: Coccidiodomycosis is a systemic infection caused by Coccidioides immitis, a dimorphic fungus endemic in the south of the USA and the north of Mexico. The disease usually affects the lungs. Primary cutaneous infection is extremely rare.

Fine needle aspiration biopsy diagnosis of metastatic neoplasms of the breast. A three-case report.

Metastases to the breast are unusual lesions that make up approximately 2% of all malignant mammary neoplasms and may mimic both benign and malignant primary neoplasms from a clinical point of view, as well as in imaging studies. Arriving at a correct diagnosis is therefore essential in order to establish appropriate management. We present three cases of metastatic neoplasms diagnosed through fine needle aspiration biopsy and immunocytochemistry.

Cutaneous leiomyomatosis and parotid pleomorphic adenoma.

We present a case of cutaneous leiomyomas (CL) arising in a pleomorphic adenoma (PA) of the parotid gland. PA and CL are benign tumors arising from the parotid gland and the erector pilli muscle, respectively. They both have a benign clinical course and in most cases leiomyomas are multiple in nature.
