We conducted gross and microscopic characterizations of lesions in Cnidaria from Palmyra Atoll, Central Pacific. We found growth anomalies (GA) to be the most commonly encountered lesion. Cases of discoloration and tissue loss were rare. GAs had a focal or multi-focal distribution and were predominantly nodular, exophytic, and umbonate. In scleractinians, the majority of GAs manifested as hyper...

Case: A 54-year-old woman was visited with a history of asymptomatic gray-brown discoloration of the facial skin at our dermatology clinic. The lesions first appeared on her chin and then became progressively darker and extended to her nose and, to a lesser extent, to the periphery of her face over a period of five years. She mentioned that the lesions worsened with heat and sun exposure. Her p...

Acute gastrointestinal necrosis (AGN) can result from multitude of local or systemic factors. The distribution of necrosis is likely to depend on the site of the insult and/or the vascular supply of the affected bowel. A rare syndrome of “Acute esophageal necrosis” (AEN) or “Black esophagus” (BEs) has been described earlier referring to black discoloration of esophageal mucosa seen on endoscopi...

Abstract We report for the first time occurrence of an Eutypella species on cotton in New South Wales (NSW), Australia. The putative was isolated from dead plants that exhibited atypical symptoms either Fusarium or Verticillium wilt. Dead had resembling lightning strike damage with blackened outer bark around fifth node zone. Internal vascular discoloration reddish grey and often occurred V-sha...

BACKGROUND We describe a rare case of diffuse macroscopic discoloration and chemical gastritis due to chronic bromazepam intake. The chemical composition of pharmaceuticals has to be considered at endoscopy and it is evident that some chemical substances damage the epithelial tissue and lead to clinical symptoms. CASE PRESENTATION Endoscopy was performed in an 82-year-old patient due to gastr...

Cucumber (Cucumis sativus L.) wilt is an important disease caused by Fusarium oxysporum. The prevalent in most of the countries world with yield losses ranging from 40–70%. Characteristic symptoms include pre and post-emergence damping-off, stunting, chlorosis, necrosis finally wilting older leaves brown vascular discoloration. Two formae speciales F. oxysporum have been described cucumber. fun...

In autoclaved greenhouse soil without Fusarium oxysporum f. sp. vasinfectum, Meloidogyne incognita did not cause leaf or vascular discoloration of 59-day-old cotton plants. Plants had root galls with as few as 50 Meloidogyne larvae per plant. Root galling was directly proportional to the initial nematode population level. Fusarium wilt symptoms occurred without nematodes with 77,000 fungus prop...

Tomato fruits grown in greenhouses were collected from Al–Karj region during summer 2008. Seven bacterial isolates that characterized as Gram negative, short rod–shaped, yellow-pigmented bacterium were isolated and recovered from the internal discoloration tissue of there collected fruits. Symptoms of infected fruits were blackening of the vascular vessels of tissue reached to seeds and lack an...

Raynaud's of the tongue following radiation alone or chemoradiotherapy (CRT) is a rare occurrence. The present study reports a case where typical symptoms and signs of Raynaud's phenomenon involving the tongue occurred ~18 months following CRT treatment in a 53-year-old female, who was a smoker prior to CRT with stage T2N2cM0 local-regional advanced stage IV oropharyngeal cancer. The patient wa...

This study aims to isolate and identify the causal pathogen of tomato bacterial wilt in Egypt. In 2008, tomato plants showing typical symptoms of bacterial wilt disease with no foliar yellowing were observed in Minia, Assiut and Sohag governorates, Egypt. When cut stems of symptomatic plants were submerged in water, whitish ooze was evident and longitudinal sections showed a brown discoloration...
