A pilonidal sinus is most commonly seen in the sacrococcygeal region. Here we describe a rare case of pilonidal sinus of the neck following trauma due to shaving. Excision of the sinus with primary repair resulted in complete healing of the lesion with no recurrence. The possible pathogenesis of this acquired condition is also discussed.
Necrotizing fasciitis is a rare microbial soft tissue infection characterized by rapidly spreading areas of necrosis and a high mortality rate. It may be of odontogenic or traumatic origin or may arise from insect bites, burns or surgical infections. We present a clinical case of an eight-year-old child with facial and cervical necrotizing fasciitis as a complication of chronic suppurative otitis media. The causes, diagnosis and management of necrotizing fasciitis are reviewed.
We report an extremely rare case of a giant cell tumour of the zygomatic bone in a 36-year-old female. The tumour was excised with healthy margins. The patient is asymptomatic without any evidence of recurrence 14 months postoperatively. To our knowledge, this is only the third reported case of this tumour occurring in the zygomatic bone in the medical literature.
We report the case of an 8-year-old boy with a parotid mass diagnosed to be a leiomyosarcoma. Considering the unresectable extent of the mass, the patient was subjected to radiotherapy. The patient developed distant metastasis following the course of radiotherapy and was put on chemotherapy. The child was lost to further follow up. To our knowledge, this is the first reported case in the English-language literature of such an entity in the pediatric age group.
Tuberculous osteomyelitis of the temporal bone is a rare and dangerous entity that should be included in the differential diagnosis of infectious processes of the base of the skull. We present the case of an 11-year-old child who presented with diplopia, ear discharge and hearing loss. The radiological and histopathological findings revealed tuberculous otitis with osteomyelitis and an abscess in the petrous apex. The child responded to anti-tuberculous chemotherapy. The diagnosis and management of tuberculous osteomyelitis are discussed and a brief review of the literature is presented.
We report the case of an 18-year-old male patient who presented to us with unilateral conductive hearing loss with duplication of the lobule. An exploratory tympanotomy revealed stapes footplate fixation. A stapedotomy with insertion of a Teflon piston was performed with improvement in his hearing. We believe this is the first reported case of such an abnormality.
We report the case of a 26-year-old man who presented to us with dysphagia secondary to blunt trauma to the neck. The patient was found to have a hyoid bone fracture with pharyngeal perforation and resultant neck abscess. The patient responded to prompt surgical and medical management. We believe this to be the first report of such a case.
