Cutaneous myiasis in skin cancer and malignant wounds: a systematic review.

BACKGROUND: Cutaneous myiasis in patients with malignant wounds or skin cancer is a rare and undesirable event with limited epidemiological data. A subregister of reports, lack of education in the population, inadequate empirical treatments, and medical underestimation are components of a public health problem that threatens patients' lives. METHODS: We conducted a systematic review of the literature of cutaneous myiasis associated with malignant wounds and skin cancer, characterizing sociodemographic variables, risk factors, clinical and histological features, and treatment. Additionally, we present a demonstrative case with the adequate taxonomic evaluation. DISCUSSION: Cutaneous myiasis is an underestimated and poorly managed infestation, which can generate severe complications in oncological patients. This is the first systematic review in the literature about this clinical scenario, which provides information to the physician and clinical researcher about the epidemiological gaps and what has been published so far. CONCLUSIONS: Findings from the current review have helped to display the sociodemographic, epidemiological, and clinical behavior of myiasis in skin cancer and malignant wounds. Its contribution to the greater tumor tissue destruction is clear; however, more studies are required. The therapeutic management in these patients is equally clarified.

Angiokeratomas, not everything is Fabry disease.

INTRODUCTION: Angiokeratoma corporis diffusum are benign capillary malformations typically associated with Fabry disease and other lysosomal storage disorders. Only in a few cases they appear in healthy individuals. METHODS AND CASE: We carried out an exhaustive review of the literature on angiokeratomas and their main clinical, dermoscopy and histological features. Additionally, we reviewed the cases of healthy subjects illustrating the limitations of each case and comparing these results with our case. DISCUSSION: Angiokeratoma corporis diffusum is mostly related to Fabry disease and other lysosomal storage disorders. However, some cases may occur in apparently healthy individuals. Therefore, there is a increasing interest in its etiology, pathogenesis and clinical evaluation. CONCLUSION: This is an academic-clinical review on angiokeratomas and their main implications in daily dermatological practice. Additionally, we report the first case in the literature of angiokeratoma corporis diffusum in a healthy patient with up-to-date laboratory methods currently available. The clinician should remember that not all angiokeratoma corporis diffusum occurs with lysosomal storage disorders.
