RESUMO
Postoperative complications, exemplified by surgical site infections, are commonplace in the realm of daily surgical interventions. Conversely, certain infectious entities, such as cerebral myiasis (CM), are distinctly rare. This report elucidates the clinical presentation of a 74-year-old female afflicted with a CSF fistula, within the context of a preceding surgical microvascular decompression employing a suboccipital craniotomy approach. Notably, the course of evaluation and treatment unveiled an intraoperative manifestation of severe CM. This case report underscores the critical significance of prompt identification, precise diagnostic elucidation, and comprehensive multidisciplinary management to optimize patient outcomes in instances of CM. Furthermore, a systematic literature review on CM supplements this report, contributing to the understanding of this infrequent complication.

Ophthalmomyiasis is a rare infection seen in susceptible individuals. We report a case of orbital myiasis in squamous cell carcinoma (SCC) in a patient of xeroderma pigmentosum. On presentation, reddish brown ulcerated mass with numerous maggots in orbit were seen. Computed tomography scan showed the presence of soft tissue lesion without any bony destruction. Following debridement, emergency exenteration with sacrifice of eyelid skin was performed. The diagnosis of SCC was confirmed on histopathologic evaluation. The maggots belonged to family Calliphoridae and secondary bacterial infection with Klebsiella organism was identified. Management issues included extensive involvement requiring exenteration, non-availability of skin graft, delayed secondary healing and recurrence of pigmented lesions in skin lining of orbit. The skin grafting was avoided as it can harbour the neoplasm.

BACKGROUND: Myiasis is the infestation of tissues and organs by dipteran larvae and is endemic in tropical areas. Diagnosis usually is made by demonstration of a larva or larvae in infected tissue, generally recognizable to the naked eye. In our case, diagnosis was based on fine needle aspiration cytology (FNAC). CASE: A 59-year-old female patient with a painful neck mass was examined at an otorhinolaryngologic department after symptoms for several weeks. The lesion was found to be an absceding lymphadenitis, based on clinical symptoms, palpation and imaging (ultrasound and computed tomography). The lesion did not improve with repeated courses of antibiotics, so surgery was performed. Pus cultures collected after incision were negative, leaving origin of the inflammation undetermined. Smears from FNA of the residual mass demonstrated a worm-like pathogen alien to most European pathologists' experience. The pathogen was identified as a dipteran larva, leading to accurate etiologic diagnosis of myiasis. More scrupulous examination of the patient's history revealed she had spent her vacation in Australia, where she probably acquired the infection. CONCLUSION: Our case demonstrates the growing importance of the pathology of infectious diseases. One reason for this may be the ever-increasing possibility, frequency and distance of travel.

The parasitic nodules are part of the cutaneous manifestations of the parasitic diseases, fundamentally affect children. We report the clinic history, study by images and parasitological results of three infrequent parasitic cases in the pediatric age, which were studied with images, specially ultrasound, and this contributed somehow to the diagnosis. The final parasitological diagnoses were dirofilaria, toxocara and myiasis. The epidemiology, clinical and dermatológica! manifestations are discussed of each one.
Los nodulos parasitarios forman parte de las manifestaciones cutáneas de las enfermedades parasitarias, las cuales afectan fundamentalmente a niños. Se da a conocer la historia clínica, el estudio por imágenes y los resultados histopatológicos y parasitarios de tres casos poco frecuentes en la edad pediátrica, los cuales fueron estudiados con ultrasonido que contribuyó de alguna manera al diagnóstico. Los parásitos encontrados fueron dirofilaria, toxocara y una larva de mosca. Se discute la epidemiología, manifestaciones clínicas y dermatológicas de cada una de estas parasitosis.

Five patients with breast myiasis underwent mammography, and three also underwent ultrasonography (US). Mammography revealed indistinct masses in all patients, with associated pairs of microcalcifications in three. US showed each larva as a fusiform hyperechoic mass surrounded by a hypoechoic halo, which included larval movement in one patient. These imaging features of breast myiasis facilitate correct diagnosis.

A case of a 54-year-old woman who presented with a breast mass is reported. Histologically, a chronic granulomatous inflammatory response was observed. The response was associated with an organism diagnosed as a fly larva, Dermatobia hominis (human botfly). The incidence of myiasis, infestation by fly larvae, presenting as a long-standing breast mass and mimicking a neoplasm is extremely rare, especially in the United States.

A 19-year-old Japanese man in good health was found on a routine chest X-ray to have considerable lung abnormalities. An open lung biopsy was performed and 30 third-instar larvae of Megaselia spiracularis Schmitz were found in the suction tube postoperatively. This appears to be the first recorded case of lung myiasis.
