Review
The incidence of dermatitis and otitis resulting from overgrowth of M. pachydermatis is great enough that cytological sampling techniques should be considered a routine part of the dermatological examination. Because most cases of MD and Malassezia otitis cannot be grossly distinguished from bacterial pyoderma and otitis, respectively, efficiency in performing cytology testing of skin and ear canal exudate is essential to the successful diagnosis and management of pruritic skin diseases and otitis. Although Malassezia infections are rarely primary, therapy can be instituted to remove the yeast as a confounding factor while a differential diagnosis is pursued in evaluating the underlying disease process.

Review
Coccidioidomycosis is a highly prevalent disease in the Western hemisphere. It is considered one of the most virulent primary fungal infections. Coccidioides species live in arid and semi-arid regions, causing mainly pulmonary infection through inhalation of arthroconidia although many other organs can be affected. Primary inoculation is rare. Since the first case of coccidioidomycosis was reported in 1892, the skin has been identified as an important target of this disease. Knowledge of cutaneous clinical forms of this infection is important and very useful for establishing prompt diagnosis and treatment. The purpose of this article is to provide a review of this infection, emphasizing its cutaneous manifestations, diagnostic methods and current treatment.

Albino guinea pigs with abraded skin were inoculated cutaneously with 27 strains of dermatophytes from animals and humans. The same strains were inoculated i.v. in guinea pigs with intact skin. Zoophilic dermatophytes and human isolates of Trichophyton mentagrophytes var. granulare produced ringworm after cutaneous application. After i.v. inoculation, the fungus was reisolated from skin samples from a considerable number of animals with and without clinical ringworm lesions, and also from lungs, liver, and kidneys. In the lungs, hyphal aggregates were noted. Some strains produced generalized dermatophytosis affecting all parts of the skin and internal organs. T. mentagrophytes B32663, selected for further study, was inoculated i.v. in the guinea pig, rabbit, rat, mouse, and chicken. Ringworm lesions occurred in the guinea pig and rabbit; in the mouse, rat, and chicken other organs were involved. Administration by other routes did not produce a generalized infection. The infection was not self-limited and the deep-seated lesions may be responsible for the recurrence of infection.

Review
Pythium insidiosum is a protoctista and causes diseases in plants and animals. In Thailand it can cause a unique human infection of three types. The first type is a subcutaneous lesion in thalassaemic patients, with the pathological findings of a granulomatous reaction, diffuse infiltration, and oedema of the vessel walls. The patients responded to a saturated solution of potassium iodide. The second type is chronic inflammation and occlusion of blood vessels mainly in the lower extremities which results in gangrene or aneurysm formation. This type of infection is only found in thalassaemic patients and leads to amputation of the affected extremities or resection of the involved arteries. The third type is keratitis. This type of infection may or may not be associated with thalassaemia. The clinical signs and symptoms do not differentiate it from other types of myocotic keratitis. The patients end up with keratoplasty, evisceration or enucleation. Thailand is an agricultural country, and there are plenty of swampy areas and several plants to support the life cycle of Pythium. Moreover, many people suffer from thalassaemia, and there is no drug available for Pythium. Pythiosis plays an important role in medicine in Thailand.

Blastomycosis is a fungal disease with an endemic area identical to that of histoplasmosis in the United States. Disease states range from a subclinical pulmonary illness to a rapidly progressive and fatal disease. Cutaneous lesions are common although the lung is the portal of entry for blastomyces. The organisms are easily demonstrated with potassium hydroxide preparations of fresh sputum, pus from skin lesions, or other biologic material. Skin and serologic tests are unreliable, largely because of cross-reactivity with antigens of histoplasmosis. Because of the ever present potential for milder forms of illness to progress to severe disease, it is recommended that all patients with symptomatic or culture proven disease be treated with amphotericin B.

Review
We report here the results of the 2016 epidemiological survey of dermatomycosis in Japan. In total, 6,776 cases were analyzed as follows: dermatophytosis, 5,772 cases (85.2%); candidiasis, 757 cases (11.2%); Malassezia infection, 235 cases (3.5%); and other fungal infections, 11 cases (0.2%). In dermatophytosis, tinea pedis was the most frequent (3,314 cases: male, 1,705; female, 1,609), followed by tinea unguium (1,634 cases: male, 766; female, 868), tinea corporis (423 cases: male, 241; female, 182); tinea cruris (316 cases: male, 242; female, 74); tinea manuum (58 cases: male, 29; female, 29); tinea capitus, Celsus' kerion (26 cases: male, 19; female, 7); and tinea barbae (1 case: male, 1). The most frequent pathogen was Trichophyton rubrum. In candidiasis, candidal intertrigo was the most frequent (181 cases: male, 98; female, 83), followed by oral candidiasis (165 cases: male, 84; female, 81), genital candidiasis (119 cases: male, 45; female, 74), diaper candidiasis (113 cases: male, 49; female, 64), erosio interdigitalis (63 cases: male, 13; female, 50), onychomycosis (41 cases: male, 17; female, 24), onychia et paronychia (28 cases: male, 2; female, 26), and angular cheilitis (23 cases: male, 6; female, 17). Although the number of cases varied depending on the role of each cooperating medical institution in the area and on population composition, no significant differences in the frequencies of clinical types were observed.
