Muhammad Shahnawaz
The Professional Medical Journal , 2000,
Abstract: The radiology and ultrasound findings of androgen secreting adenoma of adrenal gland are described. A caseis presented of a female patient with hypertension, primary infertility, menstrual irregularity and virilizingsyndrome. Non functional adenomas of the adrenal gland have been found in 5% of the routine necropsiesbut functional adenoma is exceedingly rare.

Abstract: childhood adrenocortical tumors (act) are rare. in the usa, only about 25 new cases occur each year. in southern brazil, however, approximately 10 times that many cases are diagnosed each year. most cases occur in the contiguous states of s?o paulo and paraná. the cause of this higher rate has not been identified. familial genetic predisposition to cancer (p53 mutations) and selected genetic syndromes (beckwith-wiedemann syndrome) have been associated with childhood act in general but not with the brazilian counterpart. most of the affected children are young girls with classic endocrine syndromes (virilizing and/or cushing). levels of urinary 17-ketosteroids and plasma dehydroepiandrosterone sulfate (dhea-s), which are abnormal in approximately 90% of the cases, provide the pivotal clue to a diagnosis of act. typical imaging findings of pediatric act consist of a large, well-defined suprarenal tumor containing calcifications with a thin capsule and central necrosis or hemorrhage. the pathologic classification of pediatric act is troublesome. even an experienced pathologist can find it difficult to differentiate carcinoma from adenoma. surgery is the single most important procedure in the successful treatment of act. the role of chemotherapy in the management of childhood act has not been established although occasional tumors are responsive to mitotane or cisplatin-containing regimens. because of the heterogeneity and rarity of the disease, prognostic factors have been difficult to establish in pediatric act. patients with incomplete tumor resection or with metastatic disease at diagnosis have a dismal prognosis. in patients with localized and completely resected tumors, the size of the tumor has predictive value. patients with large tumors have a much higher relapse rate than those with small tumors.
Adrenocortical tumors in children
Ribeiro R.C.,Michalkiewicz E.L.,Figueiredo B.C.,DeLacerda L.
Brazilian Journal of Medical and Biological Research , 2000,
Abstract: Childhood adrenocortical tumors (ACT) are rare. In the USA, only about 25 new cases occur each year. In Southern Brazil, however, approximately 10 times that many cases are diagnosed each year. Most cases occur in the contiguous states of S o Paulo and Paraná. The cause of this higher rate has not been identified. Familial genetic predisposition to cancer (p53 mutations) and selected genetic syndromes (Beckwith-Wiedemann syndrome) have been associated with childhood ACT in general but not with the Brazilian counterpart. Most of the affected children are young girls with classic endocrine syndromes (virilizing and/or Cushing). Levels of urinary 17-ketosteroids and plasma dehydroepiandrosterone sulfate (DHEA-S), which are abnormal in approximately 90% of the cases, provide the pivotal clue to a diagnosis of ACT. Typical imaging findings of pediatric ACT consist of a large, well-defined suprarenal tumor containing calcifications with a thin capsule and central necrosis or hemorrhage. The pathologic classification of pediatric ACT is troublesome. Even an experienced pathologist can find it difficult to differentiate carcinoma from adenoma. Surgery is the single most important procedure in the successful treatment of ACT. The role of chemotherapy in the management of childhood ACT has not been established although occasional tumors are responsive to mitotane or cisplatin-containing regimens. Because of the heterogeneity and rarity of the disease, prognostic factors have been difficult to establish in pediatric ACT. Patients with incomplete tumor resection or with metastatic disease at diagnosis have a dismal prognosis. In patients with localized and completely resected tumors, the size of the tumor has predictive value. Patients with large tumors have a much higher relapse rate than those with small tumors.
Adrenal Myelolipoma

Journal of Manmohan Memorial Institute of Health Sciences , 2015, DOI: 10.3126/jmmihs.v1i4.12002
Abstract: Adrenal myelolipoma is a rare, benign, usually unilateral, endocrinologically inactive tumor composed of mainly mature adipose tissue and hematopoietic elements that resemble bone marrow. It almost always occurs within adrenal gland but they have been reported in other locations. Most patients are asymptomatic and the lesion is discovered incidentally. We report a case of 35 years old lady who had just come for regular check up with vague abdominal discomfort on right side. Radiological investigations showed a large right sided adrenal myelolipoma. Image guided fine needle aspiration cytology was done, which confirmed the diagnosis.

Masanobu Abe, Yoshiyuki Mori, Yuki Kanno, Kazuto Hoshi, Hideto Saijo, Takahiro Abe, Kazumi Ohkubo, Tsuyoshi Takato
Open Journal of Stomatology (OJST) , 2014, DOI: 10.4236/ojst.2014.49059
Abstract: Pleomorphic adenoma is the most common benign parotid gland tumor. Although its local recurrence rate is known to be high, the recurrence extending to the cervical region is rare. Here we report a case of a young female (25 years old) with pleomorphic adenoma of the parotid gland which showed multiple recurrences through facial to cervical regions over a span of eight years. We also discuss how this benign tumor with a high recurrence rate has been treated in other cases, and how it should be treated.
Mucous gland adenoma of the bronchus in a 5-year-old child: case report and review of the literature
Peres, Luiz Cesar;Castro, Eumenia Costa da Cunha;
Jornal Brasileiro de Patologia e Medicina Laboratorial , 2003, DOI: 10.1590/S1676-24442003000400015
Abstract: mucous gland adenoma is a rare benign tumor arising from the mucous secreting glands of the larger airway mucosa. the majority of the cases are seen in the bronchus, but it has also been described in the trachea or peripheral airways. the tumor is composed of mucus-secreting cells, usually forming glands that grow into the lumen as to form an obstructive mass. there is no predilection for sex or age. we report here a case seen in a 5-year-old girl, to our knowledge the youngest in the consulted literature, who presented to hospital das clínicas of faculdade de medicina de ribeir?o preto for investigation and treatment of recurrent pneumonia and lung atelectasis. bronchoscopy showed a mass obstructing the lower left bronchus and a biopsy of the lesion revealed a benign, although uncharacteristic lesion. surgical removal of the affected segment, the recommended treatment for this benign lesion, evidenced a mucous gland adenoma. the child recovered well and was completely free of disease when she was lost for follow-up when she was 6 years old.
Conns′ syndrome - atypical presentations
Hari Kumar KVS,Jha Sangeeta,Jha Ratan,Modi K
Saudi Journal of Kidney Diseases and Transplantation , 2009,
Abstract: Primary hyperaldosteronism (Conns′ syndrome) commonly presents with a combi-nation of clinical features of hypokalemia and hypertension. Atypical presentations like normo-tension, normokalemia and neurological ailments are described in few cases. We encountered two such cases, the first presenting with acute neurological complaint and second case having insig-nificant hypertension. Both the patients had a characteristic biochemical and imaging profile consistent with primary hyperaldosteronism and responded to surgical resection of adrenal adenoma.
