The formation and conduction of electrocardiosignals and the synchronous contraction of atria and ventricles with rhythmicity are both triggered and regulated by the cardiac conduction system (CCS). Defect of this system will lead to various types of cardiac arrhythmias. In recent years, the research progress of molecular genetics and developmental biology revealed a clearer understanding of differentiation and development of the cardiac conduction system and their regulatory mechanisms. Short stature homeobox 2 (Shox2) transcription factor, encoded by Shox2 gene in the mouse, is crucial in the formation and differentiation of the sinoatrial node (SAN)...

The aberrant expression of Vangl1 is highly correlated with dysontogenesis, especially for neural tube defects. Therefore, the ultrasensitive detection of Vangl1 would provide a new approach for the specific early diagnostics in dysembryoplasia. However, no quantitative detection method is currently available. Herein, we describe the development of a new approach to fill this assay gap. We utilized C60-templated AuPt bimetallic nanoclusters for signal amplification because the promising C60 nanomaterial provides a large surface area for the in site reduction of bimetallic nanocomposites as well as excellent conductivity...

Neurological symptoms in a patient with large congenital melanocytic naevus are highly suggestive of cerebromeningeal melanoma metastasis. The presence of melanocytic cells in cerebrospinal fluid confirms this diagnosis If their malignant nature is shared with cutaneous naevocytic cells. Conversely, neurocutaneous melanosis is diagnosed when benign melanocytosis meningitis is found in patients with multiple and/or large congenital melanocytic naevus, whether cutaneous naevus cells are benign or not, or when cerebrospinal fluid cells are malignant with benign cutaneous melanocytic naevus...

Among oral and maxillofacial diseases, the maxillary osteolytic lesions constitute a rich and investigated field to define the more appropriate diagnosis and treatment. In the maxillary region, the same tumors of the other bones (osteogenic sarcoma, chondroma, etc.) cause found together with tumors and dysembryoplasias connected with the teeth development (ameloblastoma, odontoma, odontogenic myxoma, etc.). Moreover in the medullary spaces of the bones, there are reticular and hematopoietic cells that are connected with different diseases (leucemia, myeloma, lymphoma, etc...

Maffucci syndrome is a rare dysembryoplasia associating cartilage tumors similar to enchondromas in Ollier's disease and vessel tumors. We report the case of a 50-year-old woman with Maffucci syndrome involving the lower legs who developed a variety of vascular proliferations. This patient had capillary hemangiomas, cavernous angiomas, and lymphangiomas facing the cartilage tumefactions on the thigh. Regular clinical surveillance is required for such patients due to the risk of degeneration of the enchondromas and the angiomas, but also due to the possible occurrence of other malignant tumors besides the cartilage and vessel tumors...

Several diseases of the nipple and areola have a specific dermatological presentation. They may be classified into five main categories including dysembryoplasias, mastalgia, inflammatory dermatoses, hyperkeratoses and neoplasms.

BACKGROUND: Maffucci's syndrome is a dysembryoplasia of the mesoderm, explaining the dual involvement of cartilage and vascular tissue. The risk of malignant degeneration or associated tumors is high in this uncommon disease. We report a case of Maffucci's syndrome associated with squamous cell carcinoma of the cavum. CASE REPORT: A 37-year-old man consulted for multiple angiomas and chondromas which had developed since childhood. The diagnosis of Maffucci's syndrome was obvious...

Primary osteoma cutis arises in the deeper dermis for no apparent reason and presents as mature, lamellar, and osteonic bone; secondary cutaneous osteomas are correlated with inflammatory processes, scars, or dysembryoplasia and are always composed of osteoid. Ultrastructural findings of primary cutaneous osteomas have not been reported to date. Light and electron microscopic findings of a case of primary osteoma cutis are described: mineralized areas may be divided into macrocalcification and microcalcification...

Maffucci's syndrome was first described in 1881 and results of a mesodermic dysembryoplasia, congenital but not hereditary. Pathogenic hypothesis are multiple. This syndrome is characterized by the occurrence of multiple haemangiomas in the soft tissue, and multiple enchondromas of the bones. The association of ovary tumor is however exceptional. Four cases are reported in the literature; we report the fifth case.

Smooth muscle hamartoma is an uncommon cutaneous dysembryoplasia usually diagnosed in infancy. Among the 61 cases published since 1923, 56 were congenital and 3 appeared in young adults. We report a case in which the lesions started at the age of 15 years as a papular plaque in the right mammary region of a young woman. A review of the literature showed that the usual clinical presentation is a frequently pigmented plaque made of often follicular papules and measuring 1 to 10 centimeters on average. Excessive hairiness is the most frequent sign, being observed in more than two-thirds of the cases, and Darier's pseudo-sign is present in about 53 p...
