RESUMO
Langerhans cell histiocytosis (LCH) is a rare condition that presents clinically in various ways. The cause and subsequent development of LCH are idiopathic and not fully understood. This disease is mainly seen in childhood. It is rare to have bilateral temporal bone LCH as the initial presentation. LCH can affect many organs. However, the bilateral involvement of the temporal bone is very uncommon. Therefore, we believe documenting cases of this presentation can lead to a better understanding of the epidemiology and prevalence of the disease, which can contribute to its management planning. A one-year-old boy was referred to a tertiary otolaryngology clinic with bilateral postauricular swelling, hearing loss, but no tenderness or ear discharge. During the patient evaluation, a CT scan was requested to further investigate the bilateral swelling, which showed bilateral bony destructive lesions in the temporal bone area. Next, the patient was scheduled for a biopsy of this lesion under general anesthesia. A biopsy of the right mastoid confirmed the diagnosis of LCH. The patient was started on LCH IV protocol for multifocal bone lesions (MFB) with special site induction. A follow-up fluorodeoxyglucose positron emission tomography/CT (FDG PET/CT) was performed on the whole body with the impression of mild interval improvement of the temporal bones' masses bilaterally with stable bilateral cervical lymphadenopathy. LCH is a rare pathology that requires comprehensive effort from various medical and surgical teams to reach the right diagnoses and start the patient on the best available treatment plan.
RESUMO
The entero-atmospheric fistula (EAF) is a recognized complication of open abdomen surgeries, which causes significant morbidity and mortality. This usually causes long hospitalizations and may require many surgical operations. While different methods of treatment for EAF are used, all different methods share the same goal, which is a proper closure of the fistula and the open abdomen to avoid recurrence and complications. We report a case of a 48-year-old female with a bowel perforation following an attempted open bilateral ovarian cyst drainage with cyst wall biopsy complicated by entero-atmospheric fistula treated by wound closure with vacuum-assisted pressure. In conclusion, the use of vacuum-assisted closure (VAC) to induce spontaneous healing of EAFs can provide a safe acceptable alternative to surgical treatment.
