INTRODUCTION:

Crystal violet was commonly used for the treatment of oral and vaginal candidiasis or for sterilization during operations up to the 1960s. Because crystal violet is potentially toxic to mucosal membranes, it has been replaced with other disinfectants, and crystal violet is rarely used. We report a case of chemical cystitis due to intravesical instillation of crystal violet dye.

CASE PRESENTATION:

Crystal violet dye was instilled into the bladder of a 47-year-old Japanese woman to confirm the presence of a vesicovaginal fistula. Our patient developed symptoms of gross hematuria, frequent urination and lower abdominal pain. Computed tomography showed thickening of her whole bladder wall with spotted high-density lesions. Cystoscopy demonstrated desquamated epithelial cells and a hemorrhagic bladder wall. We treated our patient conservatively with nonsteroidal anti-inflammatory drugs and glucocorticoids. During follow-up, magnetic resonance images showed that the detrusor muscle of her bladder was normal. Our patient's symptoms gradually improved and she completely recovered within six months.

CONCLUSION:

Considering the severe side effect of crystal violet, it would be better not to use this dye to examine conditions such as a vesicovaginal fistula. Magnetic resonance imaging may help to evaluate the level of damage in the bladder wall of patients with chemical cystitis.

INTRODUCTION:

Aggressive angiomyxoma is a rare myxedematous mesenchymal tumor that mainly occurs in the female pelvis and perineum. The principle of treatment for aggressive angiomyxoma is surgical excision. The tumor can be removed by local excision alone when it occurs locally on the perineum. However, it cannot be completely excised by a perineal approach alone when it passes through the perineum and pelvic bone to extend into the retroperitoneal space.

CASE PRESENTATION:

A 34-year-old Asian woman presented with a rapidly growing left perineal mass and swelling in the left gluteal region. The swelling was associated with a mild, dull pain in the left gluteal region. In the present case of bulky aggressive angiomyxoma extending to the perineum and retroperitoneal space, the authors made an inverted Y incision through the buttock, removed the coccyx and lower portion of the sacrum, and excised the retroperitoneal mass and perineal lesion through a perineal approach.

CONCLUSION:

The inverted Y incision and trans-sacral approach can provide easy access to deep retroperitoneal aggressive angiomyxoma and reduce damage to neighboring organs.

Tetralogy of Fallot is one of the most common forms of cyanotic congenital heart disease and in the absence of surgical correction it has an elevated early mortality, with most patients dying in childhood.The authors reported this case because of the unusual course of an uncorrected tetralogy of Fallot. There are only a few reports of patients with an uncorrected tetralogy of Fallot who reach an advanced age and to the best of our knowledge this is the first case report of a possible endocarditis in a patient with an uncorrected tetralogy of Fallot who is older than 70 years.The authors present a case of a 72-year-old Caucasian woman with uncorrected tetralogy of Fallot who was admitted with fever and heart failure to our Cardiology Department with possible infective endocarditis.The longevity of this patient is probably due to the association between a large ventricular septal defect, a balanced subpulmonary stenosis and to the presence of systemic hypertension. After empiric antibiotic therapy, the patient was discharged and no surgical intervention was performed due to her previous benign evolution.

Primary hypothyroidism is a well-known cause of poor linear growth in children. A rare finding with profound or long-standing disease is anterior pituitary enlargement (pituitary pseudotumor). This case highlights this uncommon finding, discusses clinical situations in which gradual dose escalation of levothyroxine may be advisable and reviews adjuvant therapies that have been previously attempted to improve final height in the setting of profound hypothyroidism.We report the case of a 13-year-old Hispanic girl initially evaluated for poor linear growth and delayed puberty, and found to have pituitary enlargement secondary to profound primary hypothyroidism. Treatment with progressive doses of levothyroxine normalized her symptoms and led to complete resolution of her pituitary findings, but she then rapidly progressed through puberty, achieving an adult height of only 142cm, significantly below her calculated mid-parental height.In cases of severe primary hypothyroidism with prolonged elevation of thyroid-stimulating hormone and pituitary pseudotumor, gradual replacement of thyroid hormone with slowly escalating doses of levothyroxine may be beneficial to prevent complications of therapy. Early recognition and treatment of hypothyroidism during childhood is essential for normal growth, as final height is invariably compromised in children with prolonged disease. Additional study is needed to determine the potential beneficial effects of gonadotropin-releasing hormone agonist and recombinant human growth hormone treatment in this setting.

Acute leukemia is rare in pregnancy. The importance of promptly diagnosing and treating this disease in pregnancy stems from its life-threatening potential, both to the mother and fetus.We report a case of relapse of acute myeloid leukemia at 23 weeks of pregnancy in a 24-year-old Albanian woman. Our patient categorically refused chemotherapy treatment, and in her 35th week of gestation, severe hemorrhagic diathesis rapidly developed. The manifestation and course of this life-threatening complication posed therapeutic challenges for the attending medical team.Based both on our experience and the results of other gynecological studies, there exists a strong indication that the earlier a patient's chemotherapy treatment begins, the better the maternal outcome. We support chemotherapy for patients who are pregnant presenting with such illness. The present case report testifies that refusal of chemotherapy by such patients is a high-risk decision.

Pleural effusions are a common clinical problem and affect about one million people in the United States and United Kingdom each year. Over 60 causes of pleural effusion have been identified; establishing the definitive aetiology can be difficult, and often requires invasive procedures. Guidelines state that macroscopic examination of the fluid should be the first step in determining the aetiology of a pleural effusion. Papillary thyroid carcinoma is an uncommon cause of malignant pleural effusion, with only 10 cases reported in the literature, their physical characteristics and composition having been rarely described. We describe for the first time a distinctive brown colour of the malignant effusion (despite centrifugation) from a rare case of metastatic papillary thyroid cancer to the pleura, associated with a high pleural fluid iodine content. Such a characteristic may be useful in expediting diagnosis of a malignant pleural effusion in the appropriate clinical context.We present the case of a 71-year-old Caucasian man with metastatic papillary thyroid cancer; a large, long-standing, right-sided pleural effusion and a 83-fold higher pleural thyroglobulin level compared to corresponding serum, supporting this malignancy as the cause of the patient's effusion. The pleural fluid had a distinctive pigmentation similar to iodine-containing antiseptic preparations. Biopsy during medical thoracoscopy confirmed metastatic papillary thyroid carcinoma. Analysis of pleural fluid showed a pleural thyroglobulin level over 80 times that of serum levels (29,000μg/L versus 350ug/L). Pleural fluid iodine content was 23,000ug/L and may account for the fluid's distinctive pigment, as iodine is an essential component in thyroglobulin and thyroid hormone synthesis.Pleural fluid pigmentation may aid diagnosis in the appropriate clinical setting. A distinctive iodine-like brown colour of pleural fluid may represent elevated iodine content and should raise consideration of metastatic thyroid cancer as a cause for a pleural effusion.

Both the isolated distal femoral epiphysiolysis and the isolated proximal tibial epiphysiolysis are the least common epiphyseal injuries. Even though they are uncommon, they have a high incidence rate of complications.We present a case with Gustilo-Anderson grade 3b open and Salter-Harris type 1 epiphysiolysis of the distal femur and proximal tibia caused by a farm machinery accident. The patient was a 10-year-old boy, treated by open reduction and internal fixation.Although distal femoral and proximal tibial growth plate injuries are rarely seen benign fractures, their management requires meticulous care. Anatomic reduction is important, especially to minimize the risk of growth arrest and the development of degenerative arthritis. However, there is a high incidence of growth arrest and neurovascular injury with these type of fractures.
