Accessory breast is a frequently seen developmental breast abnormality, commoner among Asians than Caucasians. This ectopic breast tissue shares many similarities as the normal breast tissue, and although subjected to the same pathological processes, accessory breast carcinoma is rare. As locations of the accessory breast may be variable, detection of pathological lesions through clinical examinations and standard diagnostic tools (i.e., mammogram) can be difficult. Staging and management should be tailored-made according to the location of the accessory breast as well as its known pattern of lymphatic drainage...

Hypopharyngeal cancer (HPC) is generally a rare head and neck malignancy. There are differing clinical presentations depending on the subsite location of primary tumour. Advanced HPC will have neck node metastasis particularly upper jugulodigastric nodes. We report a patient with postcricoid tumour who presented with anterior huge neck swelling mimic thyroid mass. The patient first presented to the General Surgical Unit for management of presumed thyroid lesion. She was diagnosed post-cricoid squamous cell carcinoma when further assessed by otorhinolaryngologist...

Mimicry is one of the oldest concepts in biology, but it still presents many puzzles and continues to be widely debated. Simulation of wasps with a yellow-black abdominal pattern by other insects (commonly called "wasp mimicry") is traditionally considered a case of resemblance of unprofitable by profitable prey causing educated predators to avoid models and mimics to the advantage of both (Figure 1a). However, as wasps themselves are predators of insects, wasp mimicry can also be seen as a case of resemblance to one's own potential antagonist...

INTRODUCTION: Immune-mediated necrotizing myopathies (IMNM) are characterized by progressive weakness, elevated serum creatine kinase levels, and necrotizing myopathic features on muscle biopsy. Presence of highly specific autoantibodies against signal recognition particle (SRP) or 3-hydroxy-3-methylglutaryl- coenzyme A reductase (HMGCR) can aid in recognition and confirmation of IMNMs. METHODS: We describe a boy with HMGCR-positive necrotizing myopathy and highlight the clinical features in this patient...

Antitubercular therapy (ATT)-induced hepatotoxicity is often over looked and active tuberculosis is considered a contraindication for liver transplantation, however it might be the only lifesaving option to certain patients of acute liver failure (ALF) due to ATT. We have assessed the outcome of live donor liver transplantation in ATT-induced ALF. A retrospective analysis of all the cases of ALF that underwent liver transplantation from 2006 to 2014 at the Amrita Institute of Medical Sciences was done. A total of seven (7...

OBJECTIVES: To present a challenging case of inoculatory fungal mycosis mimicking an epidermoid cyst, which may have been easily overlooked by the pathologist. METHODS: We present a case report of a 29-year-old male with a nodule on the right lower back, which was surgically excised and submitted to pathology as a ruptured epidermoid cyst. RESULTS: Histopathologic sections revealed detached soft tissue fragments containing polymorphic granulomas with abscess and suspicious-appearing spherical structures ranging in size from 50 to 200 μm...

Lizard bite is very infrequent in children. Lizards tend to avoid confrontation. Bites are only inflicted when they are manipulated or when they are cornered and feel threatened. Lizard bites may be frightening but most do not cause serious health problems. The wall lizard or gecko, found in most homes, is not poisonous at all. It only checks insect population. A two-year-old boy was brought with history of lizard bite over right hand when he was trying to capture it. The child had experienced excessive sweating and irritability within two hours of bite...

Primary epithelial tumour of the renal pelvis is a rare entity. So far, very few cases are reported in literature. Of these, mucin secreting adenocarcinomas are distinctly rare. However, mucinous cystadenocarcinoma, that too arising in a horse shoe kidney is extremely rare to be reported. Mucinous cystadenomas and carcinomas arising from the renal pelvis are regarded to be secondary to a metaplastic change in the urothelium. Here, we present a case of a 51-year-old male, who complained of abdominal pain, palpable abdominal mass, haematuria along with passage of mucoid material in the urine, with a very poorly functioning kidney...

Posttransplant lymphoproliferative disorder (PTLD) is a known complication of solid organ transplantation. Diffuse large B-cell lymphoma (DLBCL) is frequently seen in this setting. However, CD30+ DLBCL with sinusoidal pattern of involvement has not been reported in pediatric PTLD. We are reporting a 9-year-old female child presented with diffuse lymphadenopathy postheart transplantation. The pattern of involvement was suggestive of anaplastic large cell lymphoma, but the malignant cells were positive for B-cell markers and negative for anaplastic lymphoma kinase...

BACKGROUND: Colloid cyst is a gelatin-containing cyst in the brain almost always found in the third ventricle. The specific shape and location of these cysts, a round well-delineated mass in the rostral part of the third ventricle adjacent to the foramen of Monro, on imaging are the main findings for diagnosis. Several masses of the third ventricle masquerading colloid cysts on images have been reported yet. Based on different surgical approach, pre-operative misdiagnosis of colloid cyst may have great impact on prognosis...

A pathological fracture is one which occurs in diseased bone with trivial trauma or even without it. However, fracture occurring as a result of significant injury can masquerade underlying ominous bone pathology, which is highly likely to be missed in the garb of overwhelming traumatic aetiology. Pathological fracture as the manifestation of tumour in children less than 10 years of age is rare.1, 2 Fracture following significant trauma masquerading as underlying malignancy is even rarer. We report a case of 7-year-old male child, he had history of significant trauma with fracture shaft of femur, pathology was "missed" initially in the outset of trauma and on subsequent follow up it was found to be osteosarcoma...

BACKGROUND: Stiff person syndrome (SPS) is a rare neuroimmunological disorder presenting with a wide variety of signs and symptoms that mimic neuro-inflammatory diseases, such as multiple sclerosis (MS), thus delaying diagnosis. METHODS: We performed a retrospective chart review of over 100 patients with SPS who were treated at Johns Hopkins Hospital and identified five patients previously diagnosed with MS. RESULTS: Patients were female with a mean age of 53years old (range 43-64)...

The causes of posterior uveitis can be divided into infectious, autoimmune, or masquerade syndromes. Viral infections. a significant cause of sight-threatening ocular diseases in the posterior segment,, include human herpesviruses, measles, rubella, and arboviruses such as dengue, West Nile, and chikungunya virus. Viral posterior uveitis may occur as an isolated ocular disease in congenital or acquired infections or as part of a systemic viral illness. Many viruses remain latent in the infected host with a risk of reactivation that depends on various factors, including virulence and host immunity, age, and comorbidities...

Filariasis, an endemic zoonosis in the Southeast Asia region, has been reported to affect various organs as well as the central nervous system (CNS). Inflammatory reactions mimicking those from neoplastic lesions clinically and radiologically have been reported in the breast and urinary bladder. To date, a CNS manifestation of filarial infestation has been reported in the form of meningoencephalitis. The authors here present an interesting case of a young man presenting in status epilepticus, which on radiological evaluation appeared to be a glioma...

Importance: Vitamin D plays an important role in both the innate and adaptive immune systems. It has been shown to contribute to the etiology of T-cell-mediated autoimmune diseases through the upregulation of type 2 anti-inflammatory T helper cells and the suppression of type 1 T helper cells. Noninfectious uveitis is postulated to be caused by immune dysfunction. Objective: To determine whether there is an association between vitamin D levels and noninfectious anterior uveitis...

Ultrasound is considered the first-line imaging modality in the evaluation of the fallopian tubes. This chapter reviews both the physiologic and pathologic sonographic findings of the fallopian tubes and how to recognize characteristic entities. Specifically, it describes how to use ultrasound techniques to distinguish between pathologic processes including chronic versus acute pelvic inflammatory disease, as well as infertility, torsion, and malignancy. It also describes how to employ modern ultrasound techniques, such as color Doppler, three-dimensional imaging, and salpingocentesis in clinical practice...
