MYCOSES
CLASSIFICATION OFMYCOSES:

4. SUBCUTANEOUS MYCOSES :
➢ It involve in dermis or subcutaneous tissue.
➢ It is otherwise called as mycoses implantation.
➢ Because the pathogen acquire through skin by
minor cut or scratches.
➢ These infections are difficult to treated.
➢ Rhinosporidiosis , mycetoma , sporotrihosis are
general type.

5. RHINOSPORIDIOSIS :
➢ Causative agent – rhinosporidum seebari
➢ Its is chronic granulomatous disease
➢ Characterized by the development of
polypoid masses of the nasal mucosa
➢ It produce large spherules in lesion and
epithelial cells

6. PATHOGENESIS
➢ It is started life cycle in tissue as rounded and oval spore.
➢ Undergoes developmental converted mature cell.
➢ The organism develop sporangium
➢ Then spore escape from sporangium and are carried from
lymphatic cell
➢ Then form a lesion
➢ Thus lesion are found in the mucosa of the nose
➢ Lesion are initially found in flat but develop in discolored
cauliflower type of masses.
➢ Then block the respiration.

LABORATORY DIAGNOSIS

3. Histological tissue examination

8. TREATMENT :

• It doesn’t more effective one.
