Renal Clear Cell Carcinoma (RCC) comprises over 80% of renal malignancies in adults. Thyroid gland metastasis is rare in RCC. Few studies have described cases of RCC mistaken for benign arteriovenous malformation (AVM). To the best of our knowledge, an AVM arising from underlying RCC metastasis to the brain has not yet been reported. The current study presents a case of RCC metastasis to the thyroid gland, with an AVM identified to be a result of metastatic involvement in the brain. A 45-year-old African-American female presented with left-sided weakness, slurred speech, facial droop and seizure...

Chiari malformation type I (CMI) is a congenital abnormality of the cranio-cerebral junction with an estimated incidence of 1 in 1280. CMI is characterized by underdevelopment of the occipital bone and posterior fossa (PF) and consequent cerebellar tonsil herniation. The presence for a genetic basis to CMI is supported by many lines of evidence. The cellular and molecular mechanisms leading to CM1 are poorly understood. The occipital bone formation is dependent on complex interactions between genes and molecules with pathologies resulting from disruption of this delicate process...

An assessment of suicidal behaviors in the dermatology patient may be necessary in several situations: (1) in the presence of psychiatric comorbidity (major depressive disorder, body dysmorphic disorder, substance use disorder, posttraumatic stress disorder), encountered in up to 30% of dermatology patients; (2) when dermatologic symptoms ("dysmorphophobia," dermatitis artefacta) represent psychiatric pathologic conditions; (3) when psychosocial stressors (bereavement, interpersonal violence) increase the risk of suicidal behavior and exacerbate stress-reactive dermatoses (psoriasis, acne); (4) in the presence of high disease burden (chronicity, increased disease severity); (5) in instances of significant pruritus or chronic sleep disruption; (6) in the presence of facial lesions or facial scarring; (7) when social exclusion or feelings of alienation arise secondary to the skin disorder; (8) with use of medications (retinoids, biologics) for which suicidal behavior has been implicated as a possible side effect; and (9) when treating psychiatric patients experiencing a serious reaction to psychotropic medications (eg, Stevens-Johnson syndrome and anticonvulsants)...

Eyes are among the first features of the face to be noticed. Loss of an eye due to congenital, traumatic or pathologic aetiologies causes disfigurement and loss of sensory feedback. It leaves a psychological impact on the patient, thus prosthesis should be provided at the earliest to raise the spirits of the afflicted. Iris positioning is one of the important steps in fabricating customized ocular prosthesis. In facial asymmetry cases, comparison of both irises together can be a major disadvantage. This case report illustrates the use of a unique customized frame spring bow assembly to position the iris disk using the established parallelism between inter pupillary line to the horizontal plane...

Cutaneous horn is conical shape of compact keratin that resembles a miniature animal horn. Though morphologically similar to horns in animals they are histologically very different from them. It is a circumscribed, conical, hyperkeratotic dense protrusion with epithelial cornification above the skin surface in response to a wide range of underlying benign and malignant pathological changes. Though benign, a cutaneous horn holds the potential to be premalignant or malignant. In India till now six cases has been reported with cutaneous horn at various unusual sites...

Nasal Natural Killer (NK)/T cell lymphoma, commonly mentioned in the literature as Lethal Midline Granuloma (LMG) is an unusual pathology of the oro-maxillo-facial region characterized by aggressive and progressive destruction of the face, nose, palate and pharynx. This disease is now classified as a T-cell lymphoma based on modern cytogenetics, immunologic and molecular studies. However, it is mentioned in various literatures by various names. Here, we present one such clinically diagnosed, histopathologically and immunologically confirmed case of LMG, designated as NK/T cell lymphoma in a 56-year-old male...

During social interactions, people tend to automatically align with or mimic their interactor's facial expressions, vocalizations, postures, and other bodily states. Automatic mimicry might be implicated in empathy, affiliation, and empathy, and is impaired in several pathologies. Despite a growing body of literature on its phenomenology, the function and underlying mechanisms of mimicry remain poorly understood. The current review puts forward a new Neurocognitive Model of Emotional Contagion (NMEC) demonstrating how basic automatic mimicry can give rise to emotional contagion...

Takayasu's arteritis (TA) is a rare case of granulomatous arteritis which mainly involves the aorta and its large branches. Although arterial hypertension is the most common feature of the disease in both adults and children, patients with TA may present with numerous clinical manifestations. Our patient was a 45-year-old woman, known to have hypertension from 3 years earlier following assessments made for severe headache. One year after the diagnosis of hypertension, she developed a left-sided lower motor neuron facial palsy, which was treated with oral corticosteroids (Prednisolone)...

Ovarian cancer, a leading cause of death in women, typically spreads locally and rarely metastasizes to the brain or seeds the leptomeninges. We present a case of a 62-year-old woman with a history of treated ovarian cell carcinoma who developed bilateral sensorineural deafness and right-sided facial weakness and on imaging was found to have bilateral internal auditory canal (IAC) masses and leptomeningeal carcinomatosis, pathologically proven by cerebrospinal fluid cytology. We discuss her magnetic resonance imaging and positron emission tomography-computed tomography findings and review the imaging characteristics of IAC metastases...

Plexiform schwannoma (PS) is a rare variety of benign nerve sheath tumor characterized by a multinodular plexiform growth pattern. PS is usually confined to the head and neck or skin. The pre-operative diagnosis of PS is difficult, and this has lead to a common misdiagnosis as a schwannoma. In addition, studies have indicated that an incomplete resection of PS often results in tumor recurrence. Here we describe a rare case of PS presented in the parapharyngeal space. Our case involved a 36-year-old man with swelling of the pharynx, who presented with a soft cervical mass...

Prenatal exposure to environmental endocrine disruptors can affect development and induce irreversible abnormalities in both humans and wildlife. The northern part of Kibale National Park, a mid-altitude rainforest in western Uganda, is largely surrounded by industrial tea plantations and wildlife using this area (Sebitoli) must cope with proximity to human populations and their activities. The chimpanzees and baboons in this area raid crops (primarily maize) in neighboring gardens. Sixteen young individuals of the 66 chimpanzees monitored (25%) exhibit abnormalities including reduced nostrils, cleft lip, limb deformities, reproductive problems and hypopigmentation...
