obsolete superficial ascomycota mycosis

Obsolete Superficial Ascomycota Mycoses

The description of obsolete superficial Ascomycota mycoses has been largely replaced by more recent terminology and classifications. However, based on the available information, it appears that these mycoses were previously characterized by the presence of melanized fungi.

• Melanized Fungi: These fungi were associated with a wide variety of infectious syndromes, including superficial, cutaneous, subcutaneous, or systemic infections (7). They were often soil organisms and had a global distribution.
• Phaeohyphomycosis: This term referred to a group of infections caused by more than 100 species of diverse dematiaceous fungi, which are a type of Ascomycota fungus. These infections could be superficial, cutaneous, subcutaneous, or systemic (8).
• Ascomycota Fungi: The Ascomycota phylum contains true fungi that form endogenous meiospores in asci and have a restricted dikaryon. Many, but not all, Ascomycota fungi are melanized (6).

It's worth noting that the reliable species identification of Ascomycota fungi is essential for diagnosing plant diseases, verifying air quality, and other applications (9). However, due to regulatory constraints, many fungal allergen extracts have retained obsolete names, including those from the Ascomycota phylum (10).

Based on the provided context, it appears that there are various signs and symptoms associated with superficial ascomycota mycosis.

Common Symptoms

• Subcutaneous cysts and/or ulcerations [8]
• Satellite lesions [8]
• Torticollis (due to damage to the 11th cranial or spinal accessory nerve) [9]
• Slight redness and scaling, associated with itching [10]

Other Possible Symptoms

• Swelling of submucosal and facial tissues [1]
• Unpleasant vaginal odor ("musty or fishy") [4] (note: this symptom is not directly related to superficial ascomycota mycosis, but rather a different type of fungal infection)

Clinical Features

• Surface topography changes (flat, raised, heaped, folded, domed, radial grooved) [6]
• Surface pigmentation changes (white, cream, yellow, brown, pink, grey, black etc.) [6]

It's worth noting that the symptoms and signs of superficial ascomycota mycosis can vary depending on the specific type of fungus involved. However, based on the provided context, it seems that subcutaneous cysts and ulcerations are a common feature of this condition.

Based on the provided context, it appears that there are several diagnostic tests for superficial fungal infections, including those caused by ascomycota.

• Microscopy and culture: According to search result 4, these methods can be used to diagnose superficial and cutaneous mycoses. Microscopic examination of clinical specimens and cultures can help identify the causative fungus.
• Molecular phylogeny: Search result 13 mentions that molecular phylogeny can be used to study the relationships among fungi, including those causing superficial mycoses. However, it does not specifically mention diagnostic tests for ascomycota.
• Histopathological examination: Search result 14 states that diagnosis of fungal infections relies on histopathological examination of clinical specimens and cultures.

It's worth noting that search results 2 and 6 discuss the taxonomy and epidemiology of superficial mycoses, but do not specifically mention diagnostic tests for ascomycota.

In terms of specific diagnostic tests for obsolete superficial ascomycota mycosis, I couldn't find any relevant information in the provided context. However, it's possible that these tests may be mentioned in more specialized or outdated literature.

Based on the available information, it appears that there are limited treatment options for obsolete superficial Ascomycota mycosis.

According to search result [2], the first-line treatment drug is voriconazole, followed by liposomal amphotericin B (AmB). However, it's worth noting that these treatments may not be effective against all types of Ascomycota mycosis.

Search result [3] mentions that voriconazole, posaconazole, and itraconazole demonstrate the most consistent in vitro activity against this group of fungi. However, there are no standardized therapies for treating Ascomycota mycosis, and treatment modalities are still limited (search result [7]).

It's also worth noting that cases of Ascomycota mycosis have been reported to range from mild to severe (search result [8]), and itraconazole was employed in some cases at doses of 100-200 mg per day. However, the effectiveness of this treatment is unclear.

In summary, while there are some antifungal medications that may be effective against Ascomycota mycosis, such as voriconazole, posaconazole, and itraconazole, there are no standardized therapies for treating this condition, and treatment modalities are still limited.

• Voriconazole, liposomal amphotericin B (AmB), and other antifungal medications may be effective against Ascomycota mycosis [2][3].
• There are no standardized therapies for treating Ascomycota mycosis [3][7].
• Itraconazole was employed in some cases at doses of 100

Based on the provided context, it appears that you are looking for the differential diagnosis of an outdated type of superficial fungal infection caused by Ascomycota.

The differential diagnoses for this condition include:

• Sporotrichosis [number 6]
• Chromoblastomycosis [number 5 and 9]
• Cutaneous tuberculosis [number 6 and 9]
• American tegumentary leishmaniasis [number 6]
• Cutaneous nocardiosis [number 6]
• Foreign body reactions or other skin conditions that may mimic the symptoms of superficial fungal infections.

It's worth noting that Ascomycota is a phylum of fungi that includes many species, and some of these may be more relevant to modern medicine than others. However, based on the provided context, it seems that the differential diagnosis for obsolete superficial Ascomycota mycosis would include the conditions listed above.
