Myiasis is derived from the Greek word, myia, meaning fly. The term was first introduced by Hope in 1840 and refers to the infestation of live human and vertebrate animals with dipterous (two-winged) larvae (maggots) which, at least for a certain period, feed on the host's dead or living tissue, liquid body-substance, or ingested food. Myiasis is the fourth most common travel-associated skin disease and cutaneous myiasis is the most frequently encountered clinical form. ⋯ Flies that cause wound myiasis include screwworm flies such as Cochliomyia hominivorax and Chrysomya bezziana, and Wohlfahrtia magnifica. This article reviews current literature, provides general descriptions, and discusses life cycles of each species. It also gives treatment techniques and descriptions of each type of illness that results from interaction/infestation.

Progressive macular hypomelanosis (PMH), a condition of uncertain etiology, is characterized by asymptomatic hypopigmented macules, predominantly located on the trunk. To date, the study of this disease has been sporadic and there are still no clinical diagnostic criteria. The aim of this study was to investigate the histopathologic and ultrastructural characteristics of PMH, and propose the clinical diagnostic criteria of PMH. ⋯ As a result of the above findings, we discussed and summarized the PMH's clinical diagnostic criteria.
