Liposarcoma are frequently seen in the retroperitoneum. It is of four types pathologically: Well-differentiated, dedifferentiated, myxoid and pleomorphic. Well-differentiated is the most common type. Dedifferentiated has the worst prognosis. Reports of Liposarcoma arising from the intraperitoneal sites such as stomach, omentum, mesentery and sigmoid mesocolon are rare. A 47 year old gentleman presented with pain in abdomen and abdominal distention, had a provisional diagnosis of GIST, intra-peritoneal liposarcoma. Imaging revealed a well-defined encapsulated abdominal mass indicative of liposarcoma with fibrous differentiation/fibro-lipoma. On surgery a well encapsulated mass was excised completely arising from the greater curvature of stomach. The mass on histopathological examination indicated features suggestive of liposarcoma (well-differentiated) with IHC markers positive for S100, CDK4 and MDM2. A diagnosis of intraperitoneal liposarcoma form greater curvature of stomach was made. This was an exceedingly rare presentation of liposarcoma arising from the greater curvature of stomach with differential diagnosis of GIST which was ruled out with histopathological features and negative CD117 and CD34. Thus to conclude liposarcoma being quite common retroperitoneal tumor, has an exceedingly rare occurrence from intraperitoneal sites and should be taken as an exceedingly rare differential diagnosis for mass per abdomen.

Uterine lipoleiomyosarcoma is a heterologous sarcoma composed of variable proportions of malignant lipoblasts histologically corresponding to well differentiated liposarcoma and malignant smooth muscle cells corresponding to leiomyosarcoma. Finding of benign lipomatous component in a typical leiomyoma (lipoleiomyoma) is not an uncommon, however, lipoleiomyosarcoma is an extremely rare malignant tumor and only very few cases have been reported so far. We report a case of lipoleiomyosarcoma of uterine corpus in a postmenopausal woman presenting with lower abdominal pain and abdominal mass. Diagnosis of lipoleiomyosarcoma was confirmed by histopathological examination of hysterectomy specimen. This is the first case of lipoleiomyosarcoma of uterus reported from Nepal.

AbstractGossypiboma (retained surgical sponge) is a pseudotumor within the body that is composed of non-absorbable surgical material with a cotton matrix. Because the symptoms of gossypiboma usually are nonspecific and may appear years after surgery, the diagnosis of gossypiboma may be difficult because the condition may mimic a benign or malignant soft-tissue tumour in the abdomen and pelvis. A 61-year-old woman with a one-year history of left upper-quadrant pain and weight loss was referred to our center. She had undergone peptic ulcer perforation 23 year ago. Physical examination revealed dullness and palpable mass in the left upper abdomen. On examination by computed tomography (CT), a hypodense mass of 12 cm in diameter between the greater curvature of the stomach, pancreas, and splenic hilus was detected. Upon exploration, a mass lesion of 10 cm in diameter was detected between the greater curvature of the stomach and splenic hilus, which caused dense adhesions not in communication with the pancreas. It was excised and a splenectomy was performed. After a macroscopic examination, the mass lesion was diagnosed as gossypiboma. Although ultrasonography (US), CT, angiography, and magnetic resonance imaging (MRI) may be used to diagnose gossypiboma, definitive diagnosis is possibile only upon surgery or histopathological examination. As a result, when an abdominal mass is observed, surgeons should carefully investigate the patient’s past surgical history while taking the possibility of gossypiboma into consideration.

Case summary A 5-year-old neutered male domestic longhair cat was presented for the investigation of a cranial abdominal mass following a 1-month history of inappetence and lethargy. Abdominal ultrasound revealed a large cavitated mass confluent with the mesenteric aspect of the descending duodenum. At surgery, the mass was found to involve the pylorus, proximal duodenum and pancreas, and was non-resectable. Histopathological examination of surgical biopsies revealed a non-neoplastic process involving eosinophils and fibroplasia. Relevance and novel information This case report describes an uncommon feline gastrointestinal pathology with an unusual appearance that may provide an additional differential diagnosis other than neoplasia or abdominal abscess when confronted with a cavitated abdominal mass in cats.

Dermoid cyst (cystic teratoma) showing well differentiated derivatives of all three germs cell layers is a benign germ cell tumour. Ovaries remain the commonest site. Paravaginal dermoid cyst is a rare occurrence. Pre-operative diagnosis is usually difficult in majority of cases. They constitute less than 4% of all extragonadal teratomas. A 28-year old, P2L2 female presented with paravaginal cyst, 10×10cms, non-tender, soft swelling, cystic in consistency occupying posterior and left part of rectovaginal septum. Trans vaginal excision of cyst under regional anaesthesia done. Cyst was ruptured while excision showing putty material with tuft of hairs. A retrospective diagnosis of mature teratoma/paravaginal dermoid cyst was made on histopathological examination. Paravaginal dermoid cyst, a benign cystic teratoma is a very rare occurrence. Transvaginal excision of dermoid cyst under anaesthesia remains treatment of choice. Retrospective diagnosis on histopathological examination remains confirmatory as it may be missed on sonography if teeth are not present in dermoid cyst.

Abstract Background Mandibular masses caused by inflammatory processes due to bacterial infections, most common with Actinomyces bovis, are well known in herbivors. This case represents a rare differential diagnosis to common inflammatory processes which cannot be distinguished from neoplasia without detailed histopathological examination. Case presentation A large unilateral mandibular mass of a free-ranging female adult red deer (Cervus elaphus elaphus) was submitted for pathological examination. The animal had been shot due to its poor body condition. Grossly, the mandibular mass showed gingival ulceration and necrosis. Histologically, irregular strands and islands of odontogenic epithelial cells and a matrix of dentin and osteoid-like material were found, leading to the diagnosis of an odontogenic tumor. Considering the animal’s age the tumor was classified as odontoameloblastoma with secondary chronic purulent osteomyelitis. Conclusions Odontogenic tumors are rare in domestic and wildlife species and so far have not been reported in red deer. In addition to the more common inflammatory processes of the mandibula and other neoplastic diseases of the oral cavity, odontogenic tumors represent a rare differential diagnosis that must be kept in mind especially when masked by inflammatory lesions.

ABSTRACT Aim The present case describes a rare and large size of giant keratoacanthoma (KA) of pinna. Background Keratoacanthoma is a fast growing benign cutaneous tumor resembling closely to well-differentiated squamous cell carcinoma (SCC) on clinical and histopathological examination (HPE). Case report A 70-year-old male presented with a rapidly growing mass on the left ear for 9 months. Tumor was excised and sent for HPE, which revealed well-differentiated SCC with focal features of a KA. Clinical significance Differentiation of KA from SCC has been a major challenge for dermatosurgeons, especially at setups with unavailability of molecular studies. So, if the tumor is giant, nonregressing in size especially on sun-exposed sites in an elderly patient, always think of SCC and treat it by surgical excision rather than watching for a spontaneous resolution.

Fibroid Polyp

Fibroid/Leiomyoma is the most common benign tumor of the uterus, arising from uterine smooth muscle. Atypical leiomyomas are rare forms of Myoma (fibroid uterus), of which recurrent atypical leiomyoma post hysterectomy is rarer and its converting in leiomyosarcoma arising from vault is rarest.  Here we report an unusual case of a 76yrs female, with leiomyosarcoma in an atypical leiomyoma arising from vault post-hysterectomy. A 76-year-old P3L3 patient presented with pain and distension of abdomen, post hysterectomy done 4 years back for chronic inversion and cervical fibroid polyp she was diagnosed as atypical leiomyoma. Laparotomy was done with a provisional diagnosis of leiomyosarcoma. Though Rarest (0.13-0.26%), a differential diagnosis of neoplastic changes should be kept in mind in patients with atypical leiomyoma, in patients presenting with any mass/pain abdomen, irrespective of any gynaecological complaints. This case shows that though it is unexpected after hysterectomy, leiomyosarcoma has to be considered in a case of abdominal mass. Atypical leiomyoma develops approximately in one to five cases out of 1,000 women with fibroid and it getting converted in leiomyosarcoma is rarest. Hence, diagnosis of leiomyosarcoma should always be kept in mind though the patient is hysterectomised.
