Idiopathic chronic hematocele of the vaginal sac. (1/6)

We report a 39-year-old male who presented non-traumatic testicular swelling and pain. Physical examination and sonography presented a suspicion of testicular tumor and both surgical exploration and inguinal orchiectomy were performed. Hematocele may both clinically and sonographically resemble a testicular tumor. The diagnostic study of choice is magnetic resonance, establishing the diagnosis and differentiating it from neoplasms.  (+info)

Adenocarcinoma of the rete testis with uncommon presentation as haematocele. (2/6)

Adenocarcinoma of the rete testis was encountered in a 62-year-old man. The tumour was localised in the region of the testicular hilum as a greyish-white nodule that showed no involvement of the adjacent testicular parenchyma or the epididymis. On microscopical examination, there was a well-differentiated adenocarcinoma separated by fibrovascular stroma, entirely confined to the testicular hilum. This primary carcinoma of the rete testis presented as a haematocele.  (+info)

Scrotal migration of a ventriculoperitoneal shunt: a case report and review of literature. (3/6)

Ventriculoperitoneal (VP) shunt insertion may be associated with migration into the abdominal wall, gastrointestinal tract, bladder, vagina, scrotum, and mediastinum. Migration of the VP shunt into the scrotum has been rarely reported. We present a 1 year old boy with cerebrospinal fluid hydrocele due to the migration of a VP shunt catheter into the right side scrotum.  (+info)

Chronic ectopic pregnancy. (5/6)

A chronic ectopic pregnancy is a form of tubal pregnancy in which there is gradual disintegration of the tubal wall with slow and/or repeated episodes of hemorrhaging leading to the formation of a pelvic mass. A review of 22 pathologically proven cases of this entity revealed the pelvic mass to be a hematocele, or a sealed-off inflammatory mass composed of blood clots, organized hematomas, and surrounding adhesions. Sonographically, the abnormality is manifested by an extrauterine, complex mass in the adnexa(e) and cul-de-sac. The mass may obliterate uterine margins and be confused for pelvic inflammatory disease, endometriosis, or uterine leiomyomas. With an increased awareness of this entity and its mildly symptomatic and protracted clinical course, a preoperative diagnosis should be possible.  (+info)

Platelet-derived growth factor inhibits bone regeneration induced by osteogenin, a bone morphogenetic protein, in rat craniotomy defects. (6/6)

Platelet-derived growth factor (PDGF) is a potent moderator of soft tissue repair through induction of the inflammatory phase of repair and subsequent enhanced collagen deposition. We examined the effect of recombinant BB homodimer PDGF (rPDGF-BB) applied to rat craniotomy defects, treated with and without bovine osteogenin (OG), to see if bone regeneration would be stimulated. Implants containing 0, 20, 60, or 200 micrograms rPDGF-BB, reconstituted with insoluble rat collagenous bone matrix containing 0, 30, or 150 micrograms OG, were placed into 8-mm craniotomies. After 11 d, 21 of the 144 rats presented subcutaneous masses superior to the defect sites. The masses, comprised of serosanguinous fluid encapsulated by fibrous connective tissue, were larger and occurred more frequently in rats treated with 200 micrograms rPDGF-BB, and were absent in rats not treated with rPDGF-BB. The masses underwent resorption within 28 d after surgery. OG (2-256 micrograms) caused a dose-dependent increase in radiopacity and a marked regeneration of calcified tissue in a dose-dependent fashion within defect sites. However, OG-induced bone regeneration was inhibited 17-53% in the presence of rPDGF-BB. These results suggest that rPDGF-BB inhibited OG-induced bone regeneration and stimulated a soft tissue repair wound phenotype and response.  (+info)
