ABSTRACT
This case highlights the importance of histopathological examination in all cases of choristoma undergoing excision.
ABSTRACT
RESUMEN: Los quistes primarios del bazo (QPB), son lesiones poco frecuentes en patología quirúrgica; los mayores de 5 cm o sintomáticos deben ser tratados quirúrgicamente para evitar el riesgo de complicaciones. Se debe realizar un examen histopatológico para confirmar el subtipo de quiste esplénico y descartar una eventual transformación maligna del revestimiento epitelial pluripotencial. El objetivo de este manuscrito fue reportar un caso de QPB intervenido quirúrgicamente y revisar la evidencia existente respecto de sus características morfológicas, terapéuticas y pronósticas. Caso clínico: Se trata de una mujer de 18 años (MAC), que consultó por distensión abdominal progresiva, de varios meses de evolución. La tomografía abdominal reveló la existencia de una masa heterogénea de 21 cm de diámetro mayor, en relación con el colon transverso y la curva mayor gástrica. El examen intraoperatorio reveló una masa sólido-quística que surgía del mesocolon transverso. La cirugía consistió en la esplenectomía y exéresis en bloque del tumor. La paciente evolucionó de forma satisfactoria, dándose de alta al quinto día del postoperatorio. El diagnóstico de quiste epitelial esplénicose estableció en base al examen patológico de la pieza quirúrgica. Cursando su 6º mes postoperatorio sin inconvenientes. Se realizó control tomográfico, que permitió verificar un bazo supernumerario funcionante.
SUMMARY: Primary splenic cysts (PSC) are rare lesions in surgical pathology; those symptomatic, or greater than 5 cm, should be treated surgically to avoid the risk of complications. A histopathological examination should be performed to confirm the splenic cyst subtype and rule out a possible malignant transformation of the pluripotential epithelial lining. The aim of this manuscript was to report a case of PSC who had undergone surgery and to review the existing evidence regarding its morphological, therapeutic and prognostic characteristics. An 18- year-old woman (MAC), consulted for progressive abdominal distention of several months of evolution. Abdominal tomography revealed the existence of a large heterogeneous mass, 21 cm in diameter, in relation to the transverse colon and the greater gastric curve. Intraoperative examination revealed a solid cystic mass arising from the transverse mesocolon. Surgery consisted of splenectomy and in-block excision of the tumor. The patient evolved satisfactorily and was discharged on the fifth postoperative day. Diagnosis of epithelial splenic cyst was established based on the pathological examination of the surgical specimen. At six months postoperative the patient had evolved satisfactorily without complications. Following abdominal tomography control a functioning supernumerary spleen was confirmed.

Se reporta el caso de una joven con esplenomegalia, que consulta por dolor abdominal crónico en hipocondrio izquierdo. Los estudios mostraron un quiste tabicado de gran tamaño, con desplazamiento de órganos. Se realizó una esplenectomía total, confirmándose al estudio histopatológico, un quiste epitelial esplénico
We report the case of a girl with splenomegaly, who consults for chronicabdominal pain in the left hypochondrium. The studies showed a largecyst with organ displacement. A total splenectomy was performed, confirmingto the histopathological study, a splenic epithelial cyst.

PURPOSE: To report a case of a primary conjunctival epithelial cyst in the orbit. CASE SUMMARY: A 60-year-old woman was referred for evaluation of proptosis of the left eye, which had developed about 2 years earlier. Upon initial examination, a movable mass was palpated in the medial aspect of the left orbit. Magnetic resonance imaging of the orbit showed a 2.5 cm-sized, ovoid, cystic mass located between the left eyeball and the medial wall of the orbit. Excisional biopsy of the orbital mass was performed. The orbital mass was a well-circumscribed cystic lesion, adherent to the medial rectus muscle. Histological examination revealed that the cyst was lined with multiple layers of cuboidal epithelium with goblet cells. A diagnosis of primary conjunctival cyst was made. CONCLUSIONS: The possibility of primary conjunctival cyst should be considered in the differential diagnosis for an orbital cystic mass.

Cystic lesions in the accessory spleen are extremely rare and they present a challenging clinical differential diagnosis. We report here on two cases of epithelial cyst of intrapancreatic accessory spleen that mimicked pancreatic cystic tumor. In both cases, the patients underwent distal pancreatectomy under the impression of a benign cystic tumor of the pancreas. Unilocular or multilocular cysts in the pancreas tail were observed, and these were later shown to be epithelial cysts in the accessory spleen located within the pancreatic tail. The cysts were lined by columnar, cuboidal or stratified squamous epithelium.

Proliferating cutaneous epithelial cyst is classified into two subtypes, proliferating trichilemmal cyst and proliferating epidermoid cyst, depending on the mode of keratinization or the origin of the tumors. Proliferating epidermoid cyst is a subepidermal cystic tumor showing, at least in focal areas, a cystic wall lined by epithelium typically seen in epidermoid cyst. We report a case of proliferating epidermoid cyst in a 58-year old man who had a 3x4 cm sized egg shaped cystic tumor on the occipital area of the scalp. Histopathologic examination revealed the tumor was a large epidermoid cyst and a portion of epithelial proliferation projected from the cyst wall into the dermis. The epithelial proliferation was surrounded by paucicellular fibrous stroma.

Cysts of the iris may be primary lesions of either epithelial or stromal in origin, or secondary lesions after trauma or surgery. The stromal cyst is usually of primary lesion, although it could be secondary as shown in our case. We report a case of recurrent iris cyst after trauma. The patient was an 8-year-old girl. She had a penetrating injury of the involved eye three years ago. She had a similar iris cyst removed two years before this surgery. Histologically, the cyst was lined by non-keratinizing stratified squamous epithelia and subjacent fibrovascular tissue. Islands of melanin-containing epithelial cells and acellular basophilic degenerating materials were also seen in the lesion. This case represents a stromal epithelial cyst that by history appears to be of post-traumatic etiology.
