A strain of Fusarium solani was isolated from a dog showing many cutaneous and submucosal nodules and pyogranulomatous kidney lesions. Clinical isolates from this systemic infection were identified using microscopic examination and confirmed by molecular analysis.

Introduction: Primary aldosteronism (PA) accounts for ∼10% of cases of hypertension in adults, however it’s a rare disease in children. We present a rare pediatric case with PA as the initial presentation of adrenocortical multiple hormone producing tumor. Case: A 7-year-old Japanese girl, who had right-sided hypoplastic leg and foot syndactyly, presented to our hospital due to abnormal ECG of ST depression at V6 on school health check-up. She showed normal growth, no signs of virilization nor Cushingoid appearance. She had elevated blood pressure (164/98 mmHg), low potassium (2.6–3.0 mEq/L) and low cardiac ejection fraction (30–40%). Her plasma aldosterone concentration (PAC) was 441 pg/mL and aldosterone/renin ratio (ARR) was 1470. Contrast-enhanced CT and MRI showed a right adrenal mass (34×22×30 mm) with high lipid content, which led to the diagnosis of primary aldosteronism by the right adrenal adenoma. Adrenal venous sampling failed to identify localization of aldosterone production. Since the possibility of bilateral production of aldosterone remained, the girl was treated with multiple anti-hypertensive medicine including spironolactone and potassium supplementation. Although the serum potassium levels were maintained within normal range, exercise-induced PVCs occurred 6 months after first visit. Abdominal US showed no changes in size of the tumor. Ten months later, she showed gradual weight gain without growth deceleration. Twelve months later, abdominal US revealed apparent enlargement of the right adrenal mass, and MRI scan showed a 156% increase in size of the right adrenal mass (32×50×53 mm). She showed further weight gain with moon face, hirsutism and acne. Hormonal analysis revealed elevated serum and urine cortisol levels (30–40μg/dL and 269–337 μg/m2/day, respectively), and suppressed ACTH levels with no diurnal variation. Serum testosterone levels elevated to 1.00 ng/mL and serum DHEA-S to 273 μg/dL. Retrospective analysis of serum testosterone at the first visit was already mildly elevated to 0.47 ng/mL. Although no distant metastases were detected before surgery, direct liver invasion was found at right adrenal tumor rejection. Clinical Lessons: Primary aldosterone producing adenoma is extremely rare in childhood. In our case, initially the adrenal tumor produced aldosterone predominantly, and it revealed to produce glucocorticoid and androgen later on. Androgen producing adrenal tumor in children tends to have malignant nature. Although initial presentation was compatible with the primary aldosteronism, intense follow-up with detailed monitoring of various hormone levels and images, and early surgical intervention should be considered.

Context: CHARGE association consists of congenital malformation of Coloboma, Heart defect, Atresia choanae, Retarded growth and development, Genital hypoplasia, Ear anomalies and/or deafness. It is often caused by CHD7 gene mutation, which also one of the causative gene for Kallmann syndrome. The endocrine dysfunction in CHARGE association has been reported but not fully understood. Objective: To clarify the mode of growth and frequency of endocrine dysfunction in CHARGE association. Subjective: We investigated the characteristics of growth and puberty, and endocrine function in 23 children (15 males and 8 females, 0~20 years old) with CHARGE association. Results: The birthweight was from -2.74 to +1.14 SDS and the birth length was from -2.86 to +1.10 SDS. 5 children were born small for gestational age. The height below -2SDS in 18 children. GH secretion was evaluated in 11 children with short stature (-9 to -2.3SD) except for one with normal height (-0.3 SD in 6 years old girl); 5 children including one with normal stature were revealed to have GH deficiency. One short girl with GH deficiency previously showed normal GH response to provocation test at 1 year old but has developed to be GH deficient at 7 years old. Gonadotropin-releasing hormone loading tests were performed in 7 males and 3 females. Nine out of 10 children showed hypogonadotropic hypogonadism; one girl showed hypergonadotropic hypogonadism, whose ovaries were undetectable on ultrasound. Human chorionic gonadotrophin (HCG) tests were performed in 6 males with micropenis and/or cryptorchidism. Peak testosterone levels after HCG stimulation were from 0 to 6.99 ng/ml. 4 patients showed peak testosterone levels less than 1 ng/ml. Four boys showed combined gonadotropin deficiency and primary hypogonadism. Conclusions: Our data showed the diversity of endocrine function in children with CHARGE association. GH deficiency can be developed over time. Hypogonadotropic hypogonadism is common, while isolated/combined primary hypogonadism should be taken into consideration in children with CHARGE association.

We encounted a case of autosomal dominant polycystic kidney disease (ADPKD) complicated by Henoch-Schönlein purpura nephritis (HSPN). A 7-year-old-girl developed Henoch-Schönlein purpura, manifesting purpura of lower extremities and arthralgia after streptococcal infection. She showed proteinuria together with microscopic hematuria thereafter, leading to diagnosis HSPN. Existence of ADPKD was revealed by family history and MRI. Open biopsy was performed and diagnosed HSPN (ISKDC grade IIIb). She was treated by multiple drug cocktail therapy, achieving remission. To our knowledge, this association has not been reported. Renal prognosis of ADPKD may be altered by complication of HSPN, thus careful follow-up of renal function could be required for long period.
