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.”

Epidermoid cysts are common cystic lesions in the skin, ovaries, and testicles, but their occurrence in the oral cavity is uncommon. They consist of cysts delimited by a fibrous capsule without cutaneous annexes and are lined by stratified squamous epithelium. The differential diagnosis includes ranula, dermoid cysts, and lingual thyroid. Despite their benign presentation, these cysts can cause functional limitations, requiring special clinical attention for extensive lesions located in regions that preserve vital structures. This paper aims to report a case of epidermoid cyst in patient with swallowing and breathing difficulty, highlighting the clinical and surgical planning.

We report the first clinical case on the successful use of proton beam therapy in the management of malignant transformation of intracranial epidermoid cyst. A 43-year-old man was initially diagnosed as this disease with left facial paresis, hypesthesia and hypoalgesia in the territories of the trigeminal nerve. After failure of surgical interventions, he was referred to our radiation centre. We performed a postoperative proton beam therapy for treatment. We delivered a total dose of 57 GyE in 31 fractions. He tolerated the treatment well with mild acute toxicities and remained healthy and functional by 2-year follow-up postradiotherapy. No evidence of delayed radiation-induced neurotoxicity was observed.

AbstractIatrogenic implantation of squamous epithelium may result in formation of an epidermoid cyst. These cysts have been described in various sites around the head and neck following otological procedures. A case of iatrogenic epidermal cyst in the parotid region following repeated myringoplasty is reported. The clinical features and differential diagnosis are discussed.

AbstractWe present a patient with failure to thrive and severe hypotonia, who was initially suspected of having a neurometabolic disease but later diagnosed as Shwachman–Diamond syndrome (SDS), which was genetically confirmed. SDS is a multisystemic disease, which is characterized by exocrine pancreatic deficiency, bone marrow dysfunction with increased risk for malignant transformation, and skeletal abnormalities. It should be included in differential diagnosis of patients with failure to thrive and unexplained neurodevelopmental delay with neutropenia.

Hepatocellular adenomas (HCAs) are currently categorized into distinct genetic and pathologic subtypes as follows: inflammatory hepatocellular adenoma, hepatocyte-nuclear-factor-1-alpha (HNF-1α-mutated) hepatocellular adenoma, andβ-catenin-mutated hepatocellular adenomas; the fourth, defined as unclassified subtype, encompasses HCAs without any genetic abnormalities. This classification has accepted management implications due to different risks of haemorrhage and malignant transformation of the four subtypes. Imaging guided biopsy and/or surgical resection very important in obtaining definitive characterization; nevertheless, MRI with intra-extravascular and hepatobiliary (dual phase) agents, is an important tool not only in differential subtypes definition but even in surveillance with early identification of complications and discovery of some signs of HCA malignant degeneration. Inflammation, abnormal rich vascularisation, peliotic areas, and abundant fatty infiltration are pathologic findings differently present in the HCA subtypes and they may be detected by multiparametric MRI approach. Lesion enlargement and heterogeneity of signal intensity and of contrast enhancement are signs to be considered in malignant transformation. The purpose of this paper is to present the state of the art of MRI in the diagnosis of HCA and subtype characterization, with particular regard to morphologic and functional information available with dual phase contrast agents, and to discuss differential diagnosis with the most common benign and malignant lesions mimicking HCAs.

Purpose. Pseudoepitheliomatous hyperplasia at the limbus can mimic an ocular surface squamous neoplasia. It is an uncommon manifestation of vernal keratoconjunctivitis and has been reported previously in limbal VKC. It, however, has not been reported as a manifestation in the palpebral form of the disease and needs to be kept in the differential diagnosis of a limbal mass lesion in vernal keratoconjunctivitis.Case Report. We report the case of a 24 year old male patient having palpebral VKC and presenting with a papillomatous limbal mass with focal areas of keratinization mimicking an ocular surface squamous neoplasia. An excision biopsy was performed, and the specimen sent for histopathologywhich revealed features of pseudoepitheliomatous hyperplasia with no evidence of dysplasia or malignant transformation. The subepithelium revealed a dense plasma-rich inflammation.Discussion. We report this relatively uncommon presentation of limbal pseudoepitheliomatous hyperplasia mimicking an ocular surface squamous neoplasia in palpebral vernal keratoconjunctivitis. Wide excision as is required for an ocular surface neoplasia may thus be avoided if this entity is recognized in vernal keratoconjunctivitis.

Objective: To investigate the ultrasonogram characteristics of common lumps in hand and foot, pursuing for greater understanding of hand and foot lumps. Methods: 65 cases of ultrasonographic characteristics of lumps in hand and foot were retrospectively analyzed, including the location, size, shape, boundary, internal echo and posterior echo, surrounding relationship and blood flow. Results: Among 65 cases, there were 26 cases of tendon sheath cyst, 16 cases of tenosynovitis giant cell tumor, 10 cases of hemangioma, 4 cases of tendon sheath fibroma, 3 cases of epidermoid cyst, 2 cases of Schwannoma, 2 cases of fibrolipoma, 1 case of angiolipoma and 1 case of neurofibroma. The preoperative and postoperative pathological diagnoses of 45 cases, accounting for 69.23%, were consistent, 3 cases (4.62%) were misdiagnosed, which included that 2 cases of tenosynovitis giant cell tumor were misdiagnosed as tendon sheath cyst, 1 case of neurofibroma as epidermoid cyst, and the preoperative diagnosis of the rest 17 cases(26.15%) were indefinite. Conclusion: The high-frequency ultrasound can diagnose properties of lumps in foot and hand well, providing diagnosis basis for further treatment in clinic.
