PFLT differs from cases of typical follicular lymphoma that involve the testis in that it more often occurs in children and adolescents; involves malignant B-cells that do have the t(14:18)q32:q21) translocation; and  presents with disease that is strictly limited to the testis. While similar to pediatric-type follicular lymphoma in not involving cells that bear the t(14:18)q32:q21) translocation, PFLT differs from the former disease in that it is limited to the testis and involves malignant cells that do not express Bcl2. PFTL is an extremely indolent disease which is manifested by lesions that exhibit a typical FL histology or, more commonly, a mixed FL-diffuse large cell lymphoma histology. It usually involves a 2-4 centimeter lesion in a single testicle. Patients have been treated with removal of the involved testes followed by various standard anti-lymphoma chemotherapy regimens to attain excellent results, i.e. 100% completed remissions with no recurrence of disease in 15 child and adolescent patients observed for 4–96 months. No cases of primary follicular lymphoma of the testis have been reported to progress to t-FL. Surgery followed by less strenuous or even no chemotherapy may prove to be the optimal treatment for this disease.
Treatments
Injection of botulinum toxin A
Surgical transection of the nerve fibers (a temporary treatment)
Application of an ointment containing an anticholinergic drug such as scopolamineCochrane reviews of interventions to either prevent or treat Freys syndrome have found little or no evidence to support their effectiveness or safety, and conclude that further clinical trials are needed. Epidemiology
The condition is rare, although the exact incidence is unknown.The disorder most often occurs as a complication of the surgical removal of a parotid gland (parotidectomy). The percentage of individuals who develop Frey syndrome after a parotidectomy is controversial and reported estimates range from 30 to 50 percent. In follow-up examinations, approximately 15 percent of affected individuals rated their symptoms as severe. Frey syndrome affects males and females in equal numbers. History
It is named after Łucja Frey-Gottesman. The disorder was first reported in medical literature by Baillarger in 1853. A neurologist from Poland, Dr. Lucja Frey, provided a detailed assessment of the disorder and coined the term "auriculotemporal syndrome" in 1923. References
