Multi cystic Nephroma is a rare benign tumor of kidney occurring in adults which has clinical, radiological and morphological features causing diagnostic dilemma as it mimicks other cystic renal lesions. Distinguishing it from a cystic renal carcinoma is very important. Multicystic nephroma is usually unilateral, more common in females, presenting as a well capsulated mass lesion with multiple non communicating cysts lined by hobnailing epithelium. A similar lesion occurring in children represents a well differentiated nephroblastoma. The case presented here was a female patient complaining of pain in the left flank and had a mass lesion which was diagnosed as cystic renal cell carcinoma radiologically. The nephrectomy specimen showed a multilocular cystic mass well delineated from adjacent renal parenchyma. Histopathologically the cysts were lined by hobnail type of epithelium and separated by fibrocollagenous stroma. The stroma had hyalinised areas, chronic inflammatory cell infiltration and foci of mature adipose tissue. No atypia or mitoses were seen in the epithelium or stromal cells. Based on the histological criteria a diagnosis of multicystic nephroma was made. It is important to make a diagnosis of multicystic nephroma based on histomorpholgical criteria as it relieves the patient from the burden of a malignant lesion.

Abstract A 60-year-old Japanese woman was admitted because of the polycystic mass with right flank pain localized in the upper portion of the right kidney. Right nephrectomy was performed because the mass lesion had continuously increased in size over the past 10 years. A surgical specimen showed histology consistent with a mixed epithelial and stromal tumor, which is closely related to multilocular cystic nephroma, and was diagnosed by a defined capsule between the cystic mass lesion and normal renal tissue by CT and MRI, and histology. Localized renal cystic disease that does not have a capsule was excluded from differential diagnosis.

Craniopharyngiomas are rare benign epithelial tumours arising from the pituitary stalk or gland. The sellar and parasellar region is the most commonly involved sites but at times tumors extend below the sellar floor involving the sphenoid sinus, invade the pharynx and reach upto the nasal cavities. Here is a case of 14 years old boy presenting with nasal cavity mass leading to bilateral obstruction and he was operated to excise the mass lesion. Grossly a grayish white cystic mass lesion was obtained after excision biopsy. On cut section, cyst contained a greyish brown thick liquid like material, with the microscopic findings of densely packed nodules of well differentiated epithelium along with stellate reticulum and wet keratin consistent with the diagnosis of craniopharyngioma. Clinical features along with imaging characteristics (except site of the lesion) and histopathological findings were all consistent with primary admantinomatous craniopharyngioma,

Accessory Parotid Gland

Diagnosis of mid-cheek mass has always been a diagnostic dilemma for clinicians. The incidence of the accessory parotid gland (APG) has been well documented in the literature. However, a diverse spectrum of pathologies can arise from this accessory parotid tissue. Basal cell adenoma is a rare benign tumor that predominantly affects the parotid gland. Its occurrence in the accessory parotid gland has been documented in 9 cases till date. Surgical approaches for the management of such APG lesions have been in debate. This report documents a case of Basal Cell Adenoma arising in accessory parotid tissue in a 55-year-old woman who was treated by transoral excision. This paper also reviews previously documented cases of all APG lesions and attempts to elucidate the rationale for selecting an appropriate surgical approach.

Maxilla And Mandible

Background. Osteoblastoma is a rare benign tumor. This tumor is characterized by osteoid and bone formation with the presence of numerous osteoblasts. The lesion is more frequently seen in long bones and rarely involves maxilla and mandible. Due to its clinical and histological similarity with other bone tumors such as osteoid osteoma and fibro-osseous lesions, osteoblastoma presents a diagnostic dilemma.Case Report. Very few cases of osteoblastomas involving maxillofacial region have been reported in the literature. This case report involves osteoblastoma involving right maxilla in an 18-year-old male patient. Following detailed clinical examination, radiological interpretation, and histopathological diagnosis, surgical excision was performed. The patient was followed up for a period of 3 years and was disease free.Summary and Conclusion. Benign osteoblastoma involving jaw bones is a rare tumor. There is a close resemblance of this tumor with other lesions such as fibro-osseous lesions and odontogenic tumors and thus faces a diagnostic challenge. Surgical excision with a long-term follow-up gives good prognosis to this lesion—Benign Osteoblastoma.

Introduction. Malignant transformation is a rare complication of mature cystic teratoma, with squamous cell carcinoma as the most common malignancy (in 75% of cases). In this article we present a case of a well-differentiated squamous cell carcinoma arising in a mature cystic teratoma and discuss the morphological and clinico-pathological features of malignant transformation in teratoma. Case Report. An 80-year-old woman with symptoms of acute abdomen underwent left salpingo-oophorectomy. Gross examination showed a cystic mass measuring 20 cm in diameter, with papillary formation on its internal surface. Histology revealed a well-differentiated squamous cell carcinoma arising in mature cystic teratoma. Squamous epithelium surrounding the tumor was dysplastic. Conclusion. Squamous cell carcinoma in mature cystic teratoma is a rare pathologic event and in most cases it is an accidental pathohistological finding.

BACKGROUND: Secretory carcinoma of the endometrium, a rare subtype of endometrioid carcinoma morphologically resembles the early secretory phase of endometrium and is almost always well differentiated and carries excellent prognosis. Very few cases of secretory carcinoma have been reported in the literature till date. Case presentation:A 58 yr old obese female presented with post-menopausal bleeding. Ultrasound revealed increased endometrial thickness and endometrial biopsy showed hyperplasia without atypia in secretory transformation. Pathological examination of the hysterectomy specimen revealed features of secretory carcinoma of the endometrium as an incidental nding. CONCLUSION: Secretory carcinoma, a rare subtype of well differentiated endometrial carcinoma carries very good prognosis and morphologically mimics various pathological conditions of endometrium. Hence, this needs to be carefully evaluated morphologically in addition with immunohistochemical markers to arrive at an accurate diagnosis.

Retroperitoneal Schwannoma

Schwannoma is a benign tumour of peripheral nerve sheath. It usually arises from head, neck, and trunk. Retroperitoneal schwannoma is a rare entity, accounting for only 0.3–3% of total schwannomas. Majority of retroperitoneal schwannomas reported in literature have a diameter of 5 to 15 cm. Preoperative diagnosis is difficult due to low frequency, nonspecific clinical course, and nonspecific imaging features. Histology usually provides definitive diagnosis. Schwannomas are solitary, well-circumscribed, and noninvasive, so complete surgical excision provides good result. We report a case of a 23-year-old male, who presented with progressive abdominal distension and intermittent episodes of intestinal obstruction. CECT was suggestive of huge solid-cystic mass in abdominopelvic region. Image guided percutaneous aspiration revealed around 1 litre of frank pus and FNAC was suggestive of abscess. Exploratory laparotomy revealed a large 32 × 28 × 26 cm mass with solid and cystic components containing 1 litre of pus. Histological features of tumour were suggestive of benign schwannoma and immunohistochemistry for S-100 was positive. Postoperative recovery was uneventful. We report this case of a retroperitoneal schwannoma because of giant size, rare location, unusual presentation, and diagnostic dilemma.

Abstract Background Gangliogliomas are rare tumors of the central nervous system. They can occur anywhere in the central nervous system but are most commonly located in the temporal lobe and are mainly found in children. Anaplastic ganglioglioma can result from either de novo or transformation of a pre-existing lesion. Case presentation We report a case of de novo anaplastic ganglioglioma in the parieto occipital region, which is a rare location. A 34-year-old lady presented with features of raised intracranial pressure (ICP) with right side hemiparesis. Contrast-enhanced magnetic resonance imaging (CEMRI) of the brain showed well-defined intense heterogenously enhancing solid cystic mass lesion 5.3 × 5.2 cm in the left parieto occipital region with mass effect and midline shift. Intraoperatively, a cystic mass lesion with reddish brown nodule was seen in the left occipital lobe. Complete tumor excision was done. Microscopic and IHC examination was suggestive of anaplastic ganglioglioma. The post-operative period was uneventful. The patient received 60-Gy radiotherapy with temozolamide as adjuvant therapy, and repeat imaging showed no tumor recurrence. Conclusion Anaplastic gangliogliomas are rare tumors with parieto occipital as rare location.

✓ This 63-year-old man presented with complaints of “having a feeling of falling backward” over a 3-month period. Results of his general physical examination, laboratory studies, and neurological examination were unremarkable. A magnetic resonance image revealed a 1.8 × 1.4 × 1.2—cm enhancing mass in the posterior third ventricle just above the corpora quadrigemina. The pineal gland was found to be diffusely enlarged at operation and separable from the posterior thalamus and was totally resected. The patient had an uneventful postoperative course but continues to be somewhat confused. The lesion consisted of a remarkable chronic inflammatory cell infiltrate permeating the pineal lobules and was composed of T and B lymphocytes, macrophages, eosinophils, and mast cells. Immunoperoxidase studies did not demonstrate Langerhans cells, and a search for microorganisms was unrevealing. There was no evidence of neoplasia; results of immunostaining for germ cell markers and other tumor-associated antigens were negative.
