This document discusses subcutaneous mycoses, a type of fungal infection that involves the dermis or subcutaneous tissue. It is caused by pathogens that enter through minor cuts or scratches in the skin. Rhinosporidiosis is provided as a common example, caused by the fungus Rhinosporidium seebari. It is characterized by polypoid masses in the nasal mucosa that can block respiration. The infection is difficult to treat and is most effectively addressed through surgical excision of lesions.

•A disease cause by mycosa or mycotic organism
•A study about mycotic organism is called mycology
•Henrich antonde barg is the father of mycology

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.

7. EPIDOMOLOGY :
✓ This disease was first reported in 1990 from Argentina
✓ over 200 case have been recognized
✓ 90% of the cases are from INDIA and SRILANKA
of which are males
LABORATORY DIAGNOSIS
1. Sample collection - skin tissue
2. Staining - gram staining , endospore staining
3. Histological tissue examination

8. TREATMENT :
• This infection is treated with ETHYLSTILBAMIDE.
• It doesn’t more effective one.
• This infection is mostly treated in SURGICAL EXCISION
• The surgery is most effective and cure the disease.

9. SYMPTOM:
▪Symptom from rhinosporidiosis can start as son as two
two weeks from exposure
▪The symptom are given below such as :
1. Labored breathing
2. Nasal swelling
3. Running nose
4. Sneezing
5. Wheezing
6. Bloody nose

10. PREVENTION :
✓Avoid bathing in ponds contaminated by
animal feces.
✓Avoid contacted with infected animal
✓Avoid the contact with infected person
✓To maintain the environment in hygienic.
