Subepidermal calcified nodule is an uncommon form of calcinosis cutis, which most commonly occurs in children. It usually presents as an asymptomatic, solitary verrucous nodule on the head and neck region, but occasionally as multiple lesions. Serum calcium and phosphorus levels are usually normal. Histopathology shows well-formed homogeneous eosinophilic material and granules in the upper derm...

BACKGROUND: The presence of a hypervascular nodule in a patient with cirrhosis is highly suggestive of a hepatocellular carcinoma. CASE PRESENTATION: A 55 year old man with idiopathic refractory anaemia was addressed for the cure of a recently appeared 3.3 cm hypervascular liver nodule. The nodule was not visible on the resected fresh specimen, but a paler zone was seen after formalin fixation....

Thyroid is a butterfly-shaped gland in the front of the neck. It is found below the voice box. Thyroid nodule is one of the indicative of thyroid cancer. Nodule can be due to the growth of thyroid cells or a cyst in the thyroid gland. It is very important to differentiate between the thyroid nodule as benign or malignant. This paper presents characterization and classification of thyroid nodule...

A case of parasitic thyroid nodule is presented. The patient was a non symptomatic 53-year-old white woman, on irregular course of L-thyroxine to treat hypothyroidism due to Hashimoto's thyroiditis. Without a history of thyroid trauma or surgery, she presented a 1.6 x 0.7 x 0.5cm right pre-laryngeal lymph node-like mass which, on ultrasonography, appeared distinct from the gland. TSH, thyroid p...

CLE peptides are potentially involved in nodule organ development and in the autoregulation of nodulation (AON), a systemic process that restricts nodule number. A genome-wide survey of CLE peptide genes in the soybean glycine max genome resulted in the identification of 39 GmCLE genes, the majority of which have not yet been annotated. qRT-PCR analysis indicated two different nodulation-relate...

OBJECTIVES The pulmonary nodule is an important diagnostic and therapeutic problem. Diagnostic certainty is only obtained by histological examination. Mini-invasive surgery allows removal of the nodule with minimal sequelae for the patient. METHODS From October 1991 to December 2006, 370 resections for a pulmonary nodule were performed at our Department of General Surgery of the University of...

BACKGROUND Dupuytren's disease is a fibroproliferative disease of the hand and fingers, which usually manifests as two different phenotypes within the same patient. The disease first causes a nodule in the palm of the hand, while later, a cord develops, causing contracture of the fingers. RESULTS We set out to characterize the two phenotypes by comparing matched cord and nodule tissue from te...

Nodulation is a form of de novo organogenesis that occurs mainly in legumes. During early nodule development, the host plant root is infected by rhizobia that induce dedifferentiation of some cortical cells, which then proliferate to form the symbiotic root nodule primordium. Two classic phytohormones, cytokinin and auxin, play essential roles in diverse aspects of cell proliferation and differ...

RACETTE, S., and TORREY, J. G. 1989. Root nodule initiation in Gymnostoma (Casuarinaceae) and Shepherdia (Elaeagnaceae) induced by Frankia strain HFPGpIl. Can. J. Bot. 67: 2873-2879. Seedlings of Gymnostoma papuanum (Casuarinaceae) and Shepherdia argentea (Elaeagnaceae) were grown in water culture and inoculated with Frankia strain HFPGpIl. Root nodule initiation and early nodule development we...

The endometrial stromal nodule is a benign tumor composed of differentiated endometrial stromal cells arranged as a well circumscribed nodule with smooth non-invasive margins. They are rare neoplasms, diagnosed in most instances by microscopy. Although nodules are benign in nature, hysterectomy is the treatment of choice to enable evaluation of the tumor margins which are well demarcated in end...
