Methods: Bartholin’s Gland Carcinoma case data from QCGC were reviewed and analysed using the computer software Statistical Package for the Social Sciences 11.0. Results: Of the 12 cases four died of their disease, seven are still alive and disease free and one is alive with recurrent disease. The mean age at diagnosis was 52.8 years. Time from onset of symptoms to diagnosis averaged 5.8 months. All diagnoses were confirmed histologically. Presenting symptoms included a lump and pain. The most common presenting complaint was a lump. Treatment included surgical excision, occasional biopsy followed by radiotherapy with or without chemotherapy. In some cases radiation and chemotherapy was followed by vulvectomy of various extent. Conclusions: Bartholin’s Gland Carcinoma is a rare condition with outcome dependent on duration of symptoms, including delay in diagnosis, cell-type, cellular differentiation and the International Federation of Gynecology and Obstetrics (FIGO) classification. A Bartholin’s gland mass in a woman aged 40 years or more should be considered malignant until a biopsy proves otherwise.The incidence of Bartholin’s Gland Carcinoma in Queensland is less than that reported elsewhere but a higher proportion of squamous cell carcinomas was found in this small series.展开更多

Symptomatic cases give significant discomfort to sufferers and have a negative impact on their quality of life. Objective: To investigate the incidence, pattern of presentation and management of Barthholin’s gland cysts and abscesses in the Federal Teaching Hospital Abakaliki (FETHA) Ebonyi State, Nigeria. Methodology: This was a four-year retrospective study of cases of Bartholin’s gland cysts and abscesses in FETHA. We studied all cases of Bartholin’s gland cysts and abscesses that were managed at the Federal Teaching Hospital Abakaliki from 1<sup>st</sup> January 2012 to 31<sup>st</sup> December 2015. Results: During the study period, there were 1015 gynaecological surgical cases of which 18 were for Bartholin’s gland cysts or abscess giving an incidence of 1.78%. The mean age of the patients was 28.8 ± 5.6 years with 61% of the patients within the age range of 21 to 30 years. The commonest risk factor that was found for the occurrence of Bartholin’s gland cyst or abscess was previous history of the disease in 14 (77.8%) followed by previous history of sexually transmitted diseases 8 (44.4%). Pain was the commonest presenting symptom in 14 (77.8%) of cases. The left vulva was the commonest site of disease as noted in 15 (83.3%) of patients. Escherichia coli and Staphylococcus aureus were the commonest isolates on swabs with 16 (88.9%) and 14 (77.8%) prevalence respectively. The disease presented commonly in form of abscess as observed in 10 (55.6%) of patients. All the patients had Marsupialization as the modality of treatment. Conclusion: Symptomatic Bartholin’s gland cyst and abscess cause significant morbidity for the sufferers and decreased quality of life. Accurate diagnosis and treatment is advocated to prevent chronicity and complications. Although options of treatment abound, Marsupialization remains the mainstay of treatment in low resource setting like ours.展开更多
