Cutaneous hyperpigmentation is a well-known side effect of tetracyclines, but doxycycline-induced cutaneous hyperpigmentation has only been described in one patient with a therapeutic dosage of doxycycline, and in one patient using suprapharmacological doses. We describe four patients with cutaneous hyperpigmentation in previously unaffected skin, and speculate that this was due to treatment wi...

This is a case report of a patient who developed a nodule in one foot, which upon biopsy, was diagnosed as tungiasis, a cutaneous infestation caused by a human flea. The natural life cycle, clinical and pathological expressions are discussed.

The ability to perceive thermal changes in the surrounding environment is critical for survival. However, sensing temperature is not the only factor among the cutaneous sensations to contribute to thermoregulatory responses in humans. Sensing skin wetness (i.e. hygrosensation) is also critical both for behavioral and autonomic adaptations. Although much has been done to define the biophysical r...

Primary cutaneous actinomycosis is a rare clinical form with variable presentation. The tumoral presentation of actinomycosis as pseudocarcinomatous or sarcomatous masses is completely rare. The management of cutaneous actinomycosis needs proper antibiotic treatment and surgical resection would not be adequate alone. Herein, we report a case of primary cutaneous actinomycosis on the dorsal surf...

In areas where melioidosis is endemic, stress on the healthcare system is substantial. Because clinical manifestations are protean, the illness is difficult to diagnose, and cutaneous Burkholderia pseudomallei infections can progress to necrotizing fasciitis. While it is and uncommon complication of cutaneous melioidosis, necrotizing fasciitis is potentially fatal and requires aggressive manage...

Cutaneous mucormycosis is a rare fungal infection in children. It is commonly found in immunocompromised children. Early diagnosis is difficult and requires a very high degree of suspicion. Recommended mainstay of treatment has been amphotericin B and extensive surgical debridement which may at times require amputation if limb is involved. The authors share their experience of two cases of succ...

sarcoidosis of the skin which were initially treated as leprosy based on the histopathological features. Histological study in one patient showed perineural and perivascular granuloma adding on to the diagnostic confusion. It is very important for the clinicians to consider sarcoidosis as a possible diagnosis in a patient with clinical features that are not typical of leprosy. Histopathology al...

INTRODUCTION Cutaneous larva migrans is caused by infection with hookworm larvae in tropical and sub-tropical areas. A history of recent travel to the tropics is usually elicited. CASE PRESENTATION A case of cutaneous larva migrans is described in which symptoms did not appear until five months after travel to Tanzania. CONCLUSION Although the lesion of cutaneous larva migrans may appear im...

A 77 year old woman, with chronic immobility, developed bed sores which became infested with maggots. This progressed to cutaneous myiasis which is an uncommon complication of this particular phenomenon.
