Merkel cell carcinoma (MCC) is a rare aggressive neuroendocrine carcinoma of the skin that shows locoregional and distant metastasis. Metastasis of MCC to body cavity effusion is extremely rare; only three cases had been reported so far. Metastatic MCC in effusion cytology shows small blue round cells with fine stippled chromatin like other small blue round cell tumors such as small cell lung carcinoma or lymphoma. The diagnosis of metastatic MCC could give patients good chances to get recently advanced therapeutic options...

INTRODUCTION: Interventional oncology locoregional therapies are validated treatment modalities for primary and secondary tumors in liver, lung, kidney and bone. At this time, there is no accordance in the choice of imaging modality to assess treatment response. Morphological imaging and RECIST 1.1 criteria based on size variation are limited by several critical points. On the other hand the role of functional imaging, in particular by [18F]-fluorodeoxyglucose ([18F]-FDG) positron emission tomography (PET), in both staging and response evaluation of locoregional treatments remains unclear because of the heterogeneous nature of available data...

Carpal tunnel syndrome is one of the most common diseases in hand surgery. The gold standard in therapy is the surgical release of the carpal tunnel. We provide a brief update on the relevant pathogenesis, diagnosis and therapy and discuss questions related to minimal invasive decompression of the median nerve. Together with a review of the current literature, we report on our experiences in minimally invasive carpal tunnel release via a monoportal endoscopic access in over 700 cases. In conclusion, the endoscopic technique provides superior convalescence and patient safety is comparable to open methods...

Background The reported incidence rate of bile duct injury (BDI) during laparoscopic cholecystectomy (LC) is 0.3%. However, routine use of intraoperative cholangiography (IOC) is a controversial, due to the additional cost and radiation exposure. The aim of this study was to assess the application of fluorescence cholangiography (FC) in comparison to IOC and to LC without any intraoperative imaging. Materials and Methods This prospective study included 230 patients undergoing LC in our institution. The subjects were divided into two groups...

Background Large bone defects and losses play a crucial role in both tumour surgery and in complex primary and revision total knee replacement. The established options of cemented or uncemented long intramedullary stems are limited by large bone defects and are at risk from relatively high exposure to aseptic loosening. There is no general valid agreement on implant fixation of the distal femur. A further option is the cementless fixation method with compressive osseointegration, based on the so-called Wolff law of bone remodelling...

BACKGROUND: A rare subset of sarcoidosis, neurosarcoidosis, is reported to occur in 5-7% of sarcoid patients and can manifest in a variety of ways. The most common are facial paralysis and optic neuritis, less commonly causing cochleovestibulopathy, blindness, anosmia, and other cranial nerve (CN) palsies. The sensory deficit may be severe and psychiatric symptoms may result from the effects of the disease or steroid treatment. Although MRI-compatible cochlear implants are now available, concerns about the feasibility of recoverable hearing with cochlear implantation in these patients as well as the practical difficulty of disease monitoring due to implant artifact must be considered...

Mutations in PARK6 (PINK1) and PARK2 (Parkin) are linked to rare familial cases of Parkinson's disease (PD). Mutations in these genes result in pathological dysregulation of mitophagy, contributing to neurodegeneration. Here, we report that environmental factors causing a specific posttranslational modification on PINK1 can mimic these genetic mutations. We describe a molecular mechanism for impairment of mitophagy via formation of S-nitrosylated PINK1 (SNO-PINK1). Mitochondrial insults simulating age- or environmental-related stress lead to increased SNO-PINK1, inhibiting its kinase activity...

BACKGROUND: Although transvenous right ventricular (RV) endocardial lead placement is routine practice in clinical pacing, RV inaccessibility in certain clinical situations mandates the search for other sites. HYPOTHESIS: This study is aimed to verify whether left ventricular lead through coronary sinus is safe and efficient. METHODS: Based on a retrospective analysis of a single-center series of 4 patients with inaccessibility for RV pacing, we report on the feasibility and reliability of coronary sinus (CS) pacing via left ventricular (LV) lead, which usually is used in cardiac resynchronization therapy...

Systemic light chain amiloydosis is a rare disease. Due to its typical cutaneous lesions, dermatologists play an essential role in its diagnosis. Clinical manifestations vary according to the affected organ and are often unspecific. Definitive diagnosis is achieved through biopsy. We report a patient with palpebral amyloidosis, typical bilateral ecchymoses and cardiac involvement, without plasma cell dyscrasia or lymphomas. The patient died shortly after the diagnosis.

Ascher's syndrome consists of double lip, blepharochalasis and sometimes non-toxic thyroid enlargement. It is a rare, benign, rarely reported, and sometimes misdiagnosed condition that most often affects patients under 20 years old. The etiology remains unknown, although factors such as trauma, hormonal dysfunction and heredity have been suggested. Treatment based on surgical intervention is indicated to improve aesthetics or function. The presented case shows a patient diagnosed with Ascher's syndrome based on clinical findings such as double lip and blepharochalasis...

Syringocystadenoma papilliferum and tubular apocrine adenoma are rare benign sweat gland tumors. Syringocystadenoma papilliferum occurs alone or in association with other tumors. Although it is rare, the association of tubular apocrine adenoma with syringocystadenoma papilliferum developing in a sebaceous nevus on the scalp is well documented. However, the co-existence of these two tumors without the background of a sebaceous nevus has not been frequently reported. Syringocystadenoma papilliferum and tubular apocrine adenoma may have a histopathological overlap, but a few cases of a syringocystadenoma papilliferum combined with a tubular apocrine adenoma have been reported...

Proteus syndrome is a rare syndrome characterized by disproportionate overgrowth of limbs, multiple hamartomas, and vascular malformations. The cerebriform connective tissue nevi, also called cerebriform plantar hyperplasia, are present in most patients, and is the main characteristic of the syndrome. If present, even alone, they can be considered as a pathognomonic sign. This article reports a classic case of Proteus syndrome in a 2-year-old male patient who began to show a discrete asymmetry of the right hemibody in relation to the left one after birth, which increased over the months...

Dyshidrosiform pemphigoid is an acquired autoimmune variant of bullous pemphigoid with persistent vesicobullous eruptions localized on the palms or soles, or both. It generally occurs in the elderly and is rarely reported in childhood. Hereby, we describe the first case of dyshidrosiform pemphigoid in a 12-year-old child, which was limited to the dorsal hands and treated successfully with dapsone (diaminodiphenyl sulfone). Along with this report, we also review the clinical features of various types of dyshidrosiform pemphigoid...

Gastrointestinal stromal tumor is rare digestive tract mesenchymal tumor, most often in the wall of the stomach. It is a benign neoplasm, but it can become malignant if not treated. We report a case of gastrointestinal stromal tumor that was discovered after abdominal ultrasonography during staging of a patient with primary cutaneous amelanotic melanoma. Mutation in the tyrosine kinase receptor could explain the development of two types of tumors in the same patient.

Pigmented purpuric dermatoses are chronic vascular inflammatory conditions characterized by the presence of pigmented macules. Among its different presentations, lichen aureus is distinguished by the lichenoid conformation of its plaques and the predilection for lower limb involvement. Its segmented form is rare and difficult to control, especially in cases of symptomatic lesions. We report a rare case of segmental lichen aureus with six years of evolution associated with light itching. We also discuss the main therapeutic approaches to control the disease...
