Dermoid cyst of the urinary bladder as a differential diagnosis of bladder calculus: a case report

Abstract Background: Yolk sac tumor is a germ cell neoplasm that arises predominantly in the gonads, but can also derive from somatic neoplasms in extragonadal locations. These cases have been denominated recently as “somatically derived Yolk sac tumors”, and have been documented in several locations, although reports from the urinary tract are scarce. To our knowledge, this is the first report of a Yolk sac tumor derived from urothelial carcinoma. Case presentation: We present a unique case of a 76-year-old man with a recurrent urinary bladder tumor, initially interpreted as a high grade urothelial carcinoma with glandular differentiation. In the recurrent tumor, diverse histological patterns were identified, including glandular, hepatoid and sarcomatoid. This tumor showed positivity for AFP, GLP3 and SALL4, and negativity for CK7 and EMA. Fluorescent in situ hybridization study showed a polysomic pattern of chromosome 12. All these findings led to the final diagnosis of a Yolk sac tumor derived from urothelial carcinoma. Conclusions: Somatically derived Yolk Sac tumors should be considered in the differential diagnosis of a high grade urothelial carcinoma, particularly when glandular and other unusual patterns are observed. Key words: Yolk sac tumor, somatically derived, urothelial carcinoma, urinary bladder, case report.

Abstract Aim “For pre operative optimization and educational purposes, rare possibilities should be included in the differential diagnosis”” Material and Methods “CASE REPORT. Inguinal hernia is one of the common operations done by surgeons, often diagnosed clinically. Here we present a case of 29 year old male patient presented with inguinal swelling for 3 years. He was admitted for the surgical ward as a case of incarcerated inguinal hernia for elective repair under GA. Intra op the mass was not consistent with inguinal hernia, two other possibilities were a concern that can cause the swelling; 1) testes, which was excluded by examining the scrotum, 2) Dermoid/Epidermoid cyst which was checked by the mass content of hair and pasty fluid” Results “DERMOID CYST” Conclusions “Most surgeons depend on clinical picture in diagnosing inguinal hernia, thus even other rare possibilities should be included in the differential diagnosis. Unusual presentations of inguinal hernia should be having radiological evaluated.”

Introduction: Giant urinary bladder calculus in an adult is an uncommon entity. The number of patients with giant bladder calculi has decreased over recent years owing to wider availability of healthcare and better diagnostic modalities. Case Report: We present a case of a young adult without any history of recurrent urinary tract infections or bladder outlet obstruction with giant vesical calculus who presented to the emergency department with gross hematuria, abdominal pain, and dysuria. Investigations revealed a large calculus in the urinary bladder, and suprapubic cystolithotomy was performed. A large stone of 6.5×6×5.5 centimeters, weighing 125 grams, was removed. On follow-up, the patient was free of any symptoms and cystoscopy was normal. Conclusion: Urinary outflow obstruction must be ruled out in all patients with giant vesical calculus. Patients without any predisposing condition should be treated as a separate entity and evaluated accordingly. Multiple surgical treatment modalities are available for bladder calculus patients. Treatment is personalised as per size of stone, number of stones, and associated comorbidities.

Orbital Lesions

Periocular tumors are common in infancy. The most common periocular tumors are capillary hemangiomas, which are present in 1-2% of newborns and develop in 10%–12% of children by the age of 1 year old. Deep capillary hemangiomas may be more challenging to diagnose than superficial capillary hemangiomas and can be confused with other orbital lesions. Deep orbital hemangiomas can mimic teratoma, lymphangioma, rhabdomyosarcoma, metastatic neuroblastoma, and granulocytic sarcoma. In this paper, we describe 2 pediatric cases where previously diagnosed dermoid cyst and dacrocystocele were found to be capillary hemangiomas upon biopsy. Approaches to distinguish capillary hemangiomas from other periocular tumors are further discussed. To our knowledge, this is the first case report of periocular hemangiomas imitating a dermoid cyst and a dacrocystocele. These cases emphasize the importance of including infantile hemangiomas in the differential diagnosis of subcutaneous periocular abnormalities.

Rare Lesion

At the floor of the mouth, various types of pathological lesions may arise. Their diagnosis and differentiation are of significant clinical importance due to different course of the disease and treatment methods. This article presents a case of a 17-year-old female patient who has been diagnosed with a dermoid cyst by accident. Differential diagnosis due to a similar morphology of the lesion involved mainly a ranula. A complete resection of the lesion was performed. Histopathological examination showed a dermoid cyst, which is a rare lesion in this location.
