Quiste folicular pigmentado perianal: variante múltiple inusual / Perianal pigmented follicular cyst: unusual multiple variant

Los quistes foliculares pigmentados son quistes epiteliales muy infrecuentes. Se describen como lesiones papulares pigmentadas, de carácter benigno, que generalmente se ubican en la cabeza o cuello. Surgen de manera única, siendo la variante múltiple aún menos frecuente. A continuación, se presenta el caso de un hombre joven, con antecedentes de VIH en terapia antiretroviral, quien consultó por la presencia de múltiples lesiones perianales, asintomáticas, de larga data, cuyo resultado histológico resultó compatible con: quistes pigmentados foliculares múltiples.

Pigmented follicular cysts are a very rare epithelial cysts. They are described as a benign papular lesion, that is usually located in the head or neck. They arise as unique, being the multiple variant even less frequent. We present the case of a young man with a history of HIV in antiretroviral therapy, who consulted for the presence of multiple, long-term asymptomatic perianal lesions whose histological result was: compatible with multiple follicular pigmented cysts.

Manejo de quiste dentígero mandibular de grandes proporciones. Presentación de un caso / Management of a mandibular dentigerous cyst of great proportions. Case presentation

Introducción: El quiste dentígero o folicular es un quiste odontogénico desarrollado frecuentemente en relación con la corona de dientes no erupcionados, con mayor porcentaje de incidencia en terceros molares inferiores. Su gran potencial de crecimiento conduce a asimetrías, parestesia, desplazamiento dentario y hasta transformación neoplásica. Por este motivo, la actitud terapéutica ante el mismo reviste singular importancia. Objetivo: Mostrar el tratamiento por enucleación, en un solo tiempo quirúrgico, con evolución favorable, de un quiste dentígero mandibular de grandes proporciones y con elevado riesgo de fractura mandibular. Presentación del caso: Paciente masculino de 45 años, que acude al Servicio de Cirugía Maxilofacial por aumento de volumen en la región mandibular izquierda; en radiografía panorámica presentaba área radiolúcida unilocular de gran tamaño, que comprometía cuerpo mandibular desde el 33 hasta alcanzar 2/3 de la rama ascendente, asociada a tercer molar retenido desplazado hacia el borde inferior mandibular. Existía además reabsorción de las raíces del 34 y 35. El paciente fue tratado en un solo tiempo quirúrgico con extracciones de dientes afectados, bloqueo intermaxilar previa colocación de férulas Gunning y enucleación del quiste por abordaje cervical, conjuntamente con exéresis del diente asociado. El diagnóstico histopatológico arrojó quiste dentígero. El paciente no sufrió complicaciones y tuvo evolución favorable. Conclusiones: Los quistes dentígeros de no ser diagnosticados a tiempo, pueden ocasionar serias alteraciones. La enucleación en un mismo tiempo quirúrgico, resulta de elección como tratamiento para garantizar la no recurrencia, siempre que se adopten todas las medidas que eviten complicaciones trans y postquirúrgicas(AU)

Introduction: The dentigerous or follicular cyst is an odontogenic cyst that frequently develops in relation to a not erupted tooth crown, with a greater percentage of incidence in the lower third molars. Its great potential growth leads to asymmetries, paresthesia, dental displacement, and even neoplastic transformation. For this reason, the therapeutic behavior with regard to this problem is of great importance. Objective: To show the treatment by enucleation of a mandibular dentigerous cyst of great proportions and elevated risk of mandibular fracture, followed in a single surgical time with a favorable evolution. Case presentation: 45 years old male patient that came to Service of Maxillofacial Surgery presenting an increase in the volume of the left mandibular zone; the panoramic radiography showed an unilocular radiolucent area of a great size, which compromised the mandibular body from tooth 33 up to reaching 2/3 of the ascending branch, associated to a retained third molar displaced to the lower mandibular edge. There was reabsorption of the roots of the 34 and 35 teeth, too. The patient was treated in a single surgical time with removals of the affected teeth, intermaxillary blocking with previous placement of Gunning splints, cyst enucleation by cervical approach, and exerecis of the associated tooth. The histopathological diagnosis showed a dentigerous cyst. The patient presented no complications, and had a favorable evolution. Conclusions: The dentigerous cysts can cause serious alterations when they are not diagnosed on time. The enucleation in a single surgical time is considered an election treatment to guarantee non-recurrence, whether all measures are taken to avoid trans and post-surgical complications(AU)

Epithelial invasion of the anterior chamber - a clinico-pathologic report of three cases

1. Three cases demonstrating two forms of epithelial invasion of the anterior chamber are presented. In all the cases it is believed that inadequate wound closure was the main factor in the causation of the condition2. Differential and clinical diagnosis of epithelization of the anterior chamber is emphasized3. Preventive and therapeutic measures are suggested. (Summary)

A Stastistical Survey of Cutaneous Epithelial Cysts / 대한피부과학회지

Sixty-one cases in which the diagnosis of epithelial cysts had been made studied. The data were collected from our own clinical records and a review of all histopathologic slides of epithelial aysts that had been filed at Departrnent of Dermatology, Chosun University Hospita.l during the past g years from July, 1979 to June, 1984. The results were as follows: 1) Among the 61 cases of epithelial cysts, 41 cases were epidermal cysts, 10 cases of milia, 7 cases of steatocystoma. multiplex, 2 cases of pilar cysts and 1 case of eruptive vellus hair cyst. 2) The average age of these patients was third decade. 3) The commonest site of epidermal cyst and milium was face. Two cases of pilar cyst occurred only on the scalp. Fteatocystoma multiplex was developed on the several sites, but not on the scalp and scrotum, 4) The average diameter was 6. 5 mm for epidermal cyst, p 6 mm for milium, 3 1 mm for steatocystoma multiplex and 17 mm for pilar cyst.
