ABSTRACT
A 40 year old female Nigerian with uncontrolled diabetes mellitus was referred to a teaching hospital with four week history of facial rash that progressed to extensive ulceration of the mid face and bilateral visual loss. She had complete nasal bridge collapse, nasopalatal fistula with black eschars on the mucosa and markedly elevated fasting blood sugar. Her blood glucose was controlled on insulin, She had surgical debridement and histopathological study done revealed fungi hyphae. Systemic antifungal (ketoconazole) was given. Subsequently, she made a slow but steady progress and her wound became clean with healthy granulation tissue. Rhinocerebral mucormycosis still remains a poorly understood disease with high mortality rate. Presently, the triad of clinician's awareness, prompt initiation of treatment and timely surgical intervention represent the effective way of managing the disease.
ABSTRACT
AIM: Though many studies have examined cysts of the jaws, most of them focused on a group of cysts and only few have examined cysts based on a particular classification. The aim of this study is to review cysts of the oro-facial region seen at a tertiary health centre in Ibadan and to categorize these cases based on Lucas, Killey and Kay and WHO classifications. MATERIALS AND METHODS: All histologically diagnosed oro-facial cysts were retrieved from the oral pathology archives. Information concerning cyst type, topography, age at time of diagnosis and gender of patients was gathered. Data obtained was analyzed with the SPSS 18.0.1 version software. RESULTS: A total of 92 histologically diagnosed oro-facial cysts comprising 60 (65.2%) males and 32 (34.8%) females were seen. The age range was 4 to 73 years with a mean age of 27.99 ± 15.26 years. The peak incidence was in the third decade. The mandible/ maxilla ratio was 1.5:1. Apical periodontal was the most common type of cyst accounting for 50% (n = 46) of total cysts observed. Using the WHO classification, cysts of the soft tissues of head, face and neck were overwhelmingly more common in males than females with a ratio of 14:3, while non-epithelial cysts occurred at a 3:1 male/female ratio. CONCLUSION: This study showed similar findings in regard to type, site and age incidence of oro-facial cysts compared to previous studies and also showed that the WHO classification protocol was the most comprehensive classification method for oro-facial cysts.
ABSTRACT
Keratoameloblastoma is a very rare ameloblastoma variant defined by extensive squamous metaplasia and keratinization. There are 13 previously reported cases in the literature, with a male predilection of 3:1. A 38-year-old male presented with a painless mandibular swelling which had been progressively increasing in size for 18 months. The incisional biopsy was misdiagnosed as basaloid squamous carcinoma. Owing to financial constraints, the patient had mandibular resection a decade after first noticing the growth, during which the clinical course was essentially benign, thus casting doubt on the initial diagnosis. The final histological diagnosis for both the incisional and resection biopsy specimens was keratoameloblastoma.
