BACKGROUND: Giant sacrococcygeal teratomas (SCTs) are at risk of perinatal morbidity and mortality due to their high vascularity. Pre-operative embolization of the feeding arteries, prior to complete surgical resection, may assist in minimizing the intraoperative blood loss by occluding these feeding arteries.
CASE PRESENTATION: We present a case of a highly vascular giant SCT in a neonate, which was successfully embolized through an endovascular approach prior to surgery. The femoral artery approach was chosen, with access established using a Micropuncture introducer as a sheath. Embolization was performed using a combination of microcoils, Gelfoam slurry, and polyvinyl alcohol particles. The patient developed femoral artery spasm post-procedure, which resolved with the application of a glyceryl trinitrate patch.
CONCLUSIONS: Performing pre-operative endovascular embolization on a giant sacrococcygeal teratoma presents particular challenges, primarily due to the difficulty in assessing small vessels and the potential complications associated with this procedure. Nevertheless, this technique proves exceptionally valuable in helping the surgeon minimize blood loss during surgery, thereby reducing the risks of morbidity and mortality. Comprehensive planning for the embolization procedure is essential, encompassing the identification of potential vascular access points and alternatives, along with careful selection of the appropriate catheter.

Reconstruction of large sacral defects following tumour resection: a report of two cases

Sacral tumours often present surgical resection and reconstruction challenges. Wide resections result in large sacral defects and neoadjuvant radiotherapy impairs wound healing. The wounds need to be covered with bulky, well-vascularised, healthy tissues. We present 2 cases where large sacral defects were reconstructed following tumour resection. Both defects were reconstructed with inferiorly based, transpelvic, pedicled vertical rectus abdominis myocutaneous flaps. This is a robust flap and carries a well-vascularised muscle bulk and skin paddle. The donor site is distant from the lesion site and is thus unaffected by both the resection and radiotherapy. This is a useful flap for reconstructing large sacral defects.

Teratomas are neoplasms characterised by an abnormal growth of tissues derived from the three germinal layers. The term 'teratoma' is derived from the Greek root 'teratos', meaning monster. Germ cells develop in the embryo and subsequently become the cells that make up the reproductive system. During fetal development, these cells follow a midline path and descend into the pelvis as ovarian cells or the scrotal sac as testicular cells. The presence of germ cells in extragonadal sites is because of the failure of these cells to migrate along the urogenital ridge. Therefore, teratomas occur in order of decreasing frequency in the ovaries, testes, anterior mediastinum, retroperitoneum, sacrococcygeal region and cranium.Liver teratomas are very rare; of the 25 hepatic teratomas described in the literature, only five have occurred in adults. The majority of the cases were in female children below the age of three, mostly arising in the right lobe of liver.We report a case of an adult male with benign mature teratoma arising in the left lobe of liver, compressing the common bile duct and causing obstructive jaundice.

Fulltext Staged resection in the management of HIV-related anogenital giant condyloma acuminatum. A case report

Introduction: Giant condyloma acuminata (GCA), also known as Bushke-Lowenstein tumour, is a rare disease which affects 0.1% of the population. Although histopathologically benign, it tends to be locally destructive. The common sites of involvement include the penis and the anorectum. Due to the rarity of the disease, there is a lack of controlled studies on the optimal management of this entity. Thus, we report a case of anogenital GCA in a 40-year-old HIV-positive man.
Case presentation: A 40-year-old man presented with progressive anogenital warts associated with foul-smelling discharge and fever. He has been diagnosed with HIV and was on HAART on presentation. A warty excrescence had infiltrated the entire external genitalia, gluteals and sacral region. Serial excision was performed along with a defunctioning colostomy. The patient recovered well, and the final histopathological showed features of GCA.
Discussion: With HIV, the HPV infection goes unchecked may develop into GCA. Malignant transformation to squamous cell carcinoma may occur in more than half of the cases. A complex interaction between HIV and HPV may lead to a higher risk of recurrence even after resection. The diagnosis is usually clinical. Imaging modalities may be used in identifying the extent and depth of invasion.
Conclusion: The optimal management of anogenital giant condyloma acuminata remains to be determined. Staged surgical excision should be conducted to achieve an optimum outcome. Radical reconstructive surgery should be reserved for patients with recurrence, malignant transformation or sphincter involvement.

Spinal epidural abscess is a severe, generally pyogenic, infection of the epidural space of spinal cord or cauda equina. The swelling caused by the abscess leads to compression or vascular disruption of neurological structures that requires urgent surgical decompression to avoid significant permanent disability. We share a rare case of Klebsiella pneumoniae spinal epidural abscess secondary to haematogenous spread of previous lung infection that presented late at our centre with cauda equina syndrome that showed good short-term outcome in delayed decompression. A 50-year old female presented with one-week history of persistent low back pain with progressively worsening bilateral lower limb weakness for seven days and urinary retention associated with saddle anesthesia of 2-day duration. Magnetic resonance imaging with contrast of the lumbo-sacral region showed an intramuscular collection of abscess at left gluteus maximus and left multifidus muscle with a L3-L5 posteriorly placed extradural lesion enhancing peripherally on contrast, suggestive of epidural abscess that compressed the cauda equina. The pus was drained using the posterior lumbar approach. Tissue and pus culture revealed Klebsiella pneumoniae, suggestive of bacterial infection. The patient made immediate improvement of muscle power over bilateral lower limbs postoperative followed by ability to control micturition and defecation the 4th post-operative day. A good short-term outcome in delayed decompression of cauda equine syndrome is extremely rare. Aggressive surgical decompression combined with antibiotic therapy led to good short-term outcome in this patient despite delayed decompression of more than 48 hours.
