[source] Squamous cell carcinoma: a rare complication of dermoid cystsNEUROPATHOLOGY & APPLIED NEUROBIOLOGY, Issue 2 2002K. Ashkan Introduction:, Dermoid cysts constitute 0.3% of all brain tumours. Carcinomatous differentiation has been described only in a handful of cases. Material and methods:, A 44-year-old-man presented with a several-year history of headaches and a 5-week history of progressive visual deterioration in the left eye. Clinical examination confirmed a normal visual acuity but an impaired left visual field. A magnetic resonance imaging scan showed a lesion in the left paraclinoid area compressing the ipsilateral optic nerve. Signal characteristics of the lesion were consistent with a dermoid or epidermoid cyst. At operation, the lesion was thought to be typical of a dermoid cyst and a near-complete excision was achieved leaving behind parts adherent to the optic nerve. Histology showed invasive squamous cell carcinoma arising within the dermoid tumour. Postoperatively the patient received radiotherapy. Results:, The patient's clinical condition initially stabilized. At 15 months follow up, however, there was clinical and radiological evidence of tumour progression and he died 1 year later. Conclusion:, Squamous cell carcinoma may rarely arise from an intracranial dermoid tumour. This may hinder total excision of the lesion and confounds the prognosis. [source] Squamous cell carcinoma arising from a seminal vesicular cyst: Possible relationship between chronic inflammation and tumor developmentPATHOLOGY INTERNATIONAL, Issue 3 2002Nobuyuki Yanagisawa A case of squamous cell carcinoma arising within an acquired seminal vesicular cyst is described. A 61-year-old man was hospitalized because of hemospermia and dysuria. Under the diagnosis of a left seminal vesicular cyst, surgical resection was performed. Pathological examination revealed squamous cell carcinoma within a seminal vesicular cyst, along with squamous metaplastic foci and severe chronic inflammation. Cell proliferation, determined with reference to MIB-1 labeling indices, showed a stepwise increase from normal columnar epithelium, through squamous metaplasia, to squamous cell carcinoma. Sporadic p53 protein accumulation without evident gene mutations was also apparent in both the carcinoma and squamous metaplastic lesions. We therefore concluded that the squamous cell carcinoma might have developed from squamous metaplastic foci associated with chronic inflammatory stimulation, within a seminal vesicular cyst.
