A slowly growing flank mass

CASE PRESENTATION A 62-year-old woman presented to her family physician with a twomonth history of a slowly growing left flank mass. She was previously well except for recurrent urinary tract infections; there was no recent travel or trauma. An ultrasound demonstrated a benign-appearing left renal cyst. Three weeks later, she began to develop flank pain, fevers, chills, night sweats and erythem...

A rapidly growing gingival mass.

CLINICAL PRESENTATION A 71-year-old Korean woman was referred to the Department of Oral and Maxillofacial Surgery with a 10-day history of a rapidly growing mass occupying the oral cavity, which was associated with pain and spontaneous bleeding. Clinical examination revealed a soft or slightly firm pedunculated mass approximately 4 5 5 cm in size on the anterior aspect of the lower gingiva. The...

mediciNe & HeAltH/RHode islANd lAryngeAl ChondrosArComA Is A rAre relAtIVely slow-growIng tumor arising from the largyngeal cartilages. The slowly progressive nature of symptoms means that many patients will undergo multiple diagnostic studies, and recognition of the imaging characteristics of the tumor may assist significantly in diagnosis. We present a case of a laryngeal chondrosarcoma lacki...

Mass distribution exponents for growing trees

We investigate the statistics of trees grown from some initial tree by attaching links to preexisting vertices, with attachment probabilities depending only on the valence of these vertices. We consider the asymptotic mass distribution that measures the repartition of the mass of large trees between their different subtrees. This distribution is shown to be a broad distribution and we derive ex...
