Malignant mesenchymoma of the liver in children: a clinicopathologic and ultrastructural study.

A primary malignant mesenchymoma of the liver in a nine year old boy is reported with the results of ultrastructural investigation. In accordance with previous observations, our study indicates that this type of tumor is remarkable because of its bulky size and possible rapidly fatal outcome. Although the term malignant mesenchymoma can be applied, the tumor is primarily fibrosarcomatous and liposarcomatous. It could be postulated that this tumor and the more frequent benign mesenchymal hamartoma of the liver are two histogenetically related lesions that preferentially affect the liver in children.

Uterus-like mass replacing ovary: report of a new entity.

A unique, uterus-like ovarian mass with central endometriosis was studied. A 31-year-old woman with a ten-year history of endometriosis of the left ovary had surgically excised a left ovarian mass with a central cavity that was lined by endometriotic tissue, which was surrounded in turn by a very thick wall of smooth-muscle cells that contained a scanty amount of collagen. The general architecture of the mass simulated that of a uterus. The tentative hypothesis is that the present mass was the end result of an intensive and complete transition of the ovarian stromal cells into smooth-muscle fibers.

Primary cutaneous lymphoma with a nodular pattern in infancy.

We present the first reported case of primary lymphoma with a nodular pattern in infancy, accompanied by a detailed histopathological study. The diagnosis is based upon unquestionable histopathological data. Remarkable are the macroscopic findings of the lesion, the very young age of the patient, and the Burkitt's lymphoma-like appearance of the lesion in addition to the nodular pattern. Another case of cutaneous nodular lymphoma in an infant was previously reported by Traggis et al. but without a detailed histopathological description. These two cases, in consideration of the rarity of nodular lymphoma in children, promote speculative considerations, especially in regard to etiology and therapy.

Renal dysplasia with sacral-perineal location.

We report a case of renal dysplasia associated with a large non-renal lumbosacral and perineal mass. A huge sacral-perineal mass and malformation of the scrotum and penis were noted at birth. The mass was thought to be a lumbosacral teratoma. The patient also suffered from respiratory distress and he died 5 days after birth. At autopsy 2 small dysplastic kidneys were found. The kidneys and the sacral mass showed the same histological features of typical renal dysplasia.

Bone marrow biopsy in children: a study of 111 patients.

Closed trephine needle biopsy of the bone marrow has become an established procedure in the evaluation of many malignant and benign diseases in adults; however, its role in pediatric pathology has not yet been defined. In the period from February 1974 to April 1978 we have performed 164 such biopsies in 111 children under 15 years of age. A representative specimen has been obtained in over 80% of cases. This series included, in order of frequency, non-Hodgkin lymphomas, Hodgkin lymphomas, aplastic anemias, rhabdomyosarcomas, neuroblastomas, miscellaneous solid tumors, and single cases of histiocytosis X, malignant histiocytosis, sarcoidosis, malignant histiocytoma, and Castleman lymphoma of the hyaline-vascular type. Histology has been found superior to cytology in the detection of neuroblastoma invasion; the evaluation of the true cellularity in aplastic anemia, and the detection of granulomatous tissue in the only case of sarcoidosis. In other diseases histology and cytology gave similar information, except for the few cases of acute leukemia in partial relapse, which has been better defined in the aspirate smears than in the core specimen. Further evaluation of this technique in other patient series appears advisable.

Xanthogranulomatous lymphadenitis.

A case of an unusual type of granulomatous lymphadenitis, initially suspected of being a malignant lymphoma, is reported. Histologically, this lesion shows a striking xanthomatous appearance, due to collections of foamy histiocytes interspersed with chronic inflammatory cells, and resulting in a storage-like aspect. Evidence indicates that this process merely represents the reabsorption and healing phases of an acute suppurative lymphadenitis, with histopathologic features comparable to those of xanthogranulomatous pyelonephritis. The term xanthogranulomatous lymphadenitis is suggested for this previously inadequately described lesion, and the likely non-specific degenerative character of the xanthomatous response is stressed.

Intravascular endothelial proliferations in children.

Six children who had benign cutaneous vascular lesions characterized by papillary or solid proliferation of the endothelial cells were seen in a 16-year period. In five of them, the lesions had the histologic features of the entity originally described by Masson and recently reported by Clearkin and Enzinger as intravascular papillary endothelial hyperplasia. In one of the five, the lesion appeared in the pure form within large vascular spaces, whereas in the remaining four it appeared as a very limited focal change in a hematoma. The authors agree with others that this lesion represents a peculiar variant of an organizing thrombus. The histologic features of the lesion in the sixth patient were compatible with the so-called "intravenous atypical vascular proliferation," another pseudomalignant vascular disorder recently described by Rosai and Akerman.

Cyst of the choroid plexus of the left lateral ventricle.

A cyst of the choroid plexus of the left ventricle is described. The cyst was lined by a choroidal epithelium and filled with cerebrospinal fluid. It produced an intermittent obstructive syndrome. The cyst was almost completely invaginated into the third ventricle, simulating an expanding process in the third ventricle. After microsurgical removal, the recovery of the patient was complete. Electronmicroscopy of the cyst wall is reported. Histological and neuroradiological features are discussed.

Retroperitoneal fibrohistiocytic tumors in children: report of five cases.

Five rare retroperitoneal fibrohistiocytic tumors of children are described mainly in reference to the pathological aspects. A more detailed description is given of a retroperitoneal xanthogranuloma, including an ultrastructural study. This case is particularly interesting for its rapid transformation into a fibroxanthosarcoma. The other cases include two fibroxanthosarcomas, a storiform fibrous xanthoma, and a malignant histiocytoma. The most difficult points in the recognition and in the differential diagnosis of these tumors are discussed, and emphasis is placed on some interesting pathological features. Prognosis of such tumors appears difficult to assess from our series since two patients died in the immediate postoperative period, one died one and a half years after the discovery of the tumor, and two are alive and well, but with a short follow-up.

Peptichemio in advanced neuroblastoma.

Peptichemio (PTC) is a mixture of six synthetic peptides of m-L-phenylalanine mustard. It acts with both alkylating and antimetabolic effects, interfering with the synthesis of DNA, RNA, and proteins. PTC was administered iv to 18 previously untreated children with advanced neuroblastoma at a dose of 1-1.5 mg/kg/day for one to three cycles of 5-6 consecutive days each. Eleven of 12 patients (92%) experienced both objective and subjective improvement; complete remission was achieved in two of them. In spite of the high remission rate, the median duration of remission has been short (4 months) and the overall survival (median, 6 months) did not seem to be influenced by the use of PTC. The primary toxic effects were, in order of importance, bone marrow depression, phlebosclerosis, nausea and vomiting, and alopecia. Chronic use of PTC seems limited by two major factors: profound long-lasting thrombocytopenia and severe phlebosclerosis.

Wilms' tumor after treatment.

Sixty-one Wilms' tumors (WTs) from 59 patients who received preoperative therapy were studied. Twenty-seven WTs from 26 patients who did not receive preoperative treatment were also reviewed as controls. Marked and diffuse morphological changes occurred in treated cases. Necrosis affected mostly undifferentiated and replicating elements and was extensive, up to 90% of tumor mass. Minimal residual tumor, permitting recognition as Wilms', was always spared. Epithelial and rhabdomyoblastic components were more resistant to treatment; moreover, they appeared to be susceptible to differentiation and maturation. Necrosis and muscle cell differentiation seemed to have prognostic implications. Cases with extensive necrosis (greater than 90%) had a better outcome, although the difference was not statistically significant. The rhabdomyoblast/tumor mass ratio, after treatment, appears to carry prognostic meaning. Chemotherapy had no apparent effect on anaplasia.

[Ewing's sarcoma. Results of treatment in 16 consecutive cases].

In the period January 1974-August 1981, 16 previously untreated cases of Ewing's Sarcoma have been diagnosed at the Giannina Gaslini Children's Hospital Genova. Eight were male, eight female. Median age at diagnosis was 11 years. Two patients presented with a unique metastatic lesion, in the right lung and in an illiac lymph node, respectively. Fourteen patients have been initially treated with local radiotherapy (dosages ranging form 4,800 to 6,600 rads) in association with antiblastic polichemotherapy utilizing 4 drugs (Adriamycin, Actinomycin D, Vincristine, Cyclophosphamide). The Rosen et al.'s T-2 protocol was adopted, modifying the initial phase in order to give more weight to Adriamycin and reduce the toxic effects related to radio-chemotherapy combination. Two patients bearing a costal primary were immediately treated with a more complex and aggressive chemotherapy (T-6 Protocol), followed by local irradiation (in one case preceded by surgical ablation) and then chemotherapy again (T-2 protocol, second phase) for 10 months. Treatment determined a fast subjective relief in the 13 symptomatic patients. All 16 cases achieved a status of complete remission. Four of them subsequently relapsed: locally in two, in distant sites in the remaining 2. All 4 died 12-27 months form diagnosis. Twelve patients are presently alive without evidence of disease at 3-92 months (median 37 months) following diagnosis. Treatment has caused early and delayed toxicity in all cases. However, the entity of these complications varied considerably from one patient to an other. Age at diagnosis and site of primary tumor were the factors most relevant in this respect.
