    Probabilistic computation of Poiseuille flow velocity fields (1995)

    Notes: Velocity fields for Poiseuille flow through tubes having general cross section are calculated using a path integral method involving the first-passage times of random walks in the interior of the cross sectional domain D of the pipe. This method is applied to a number of examples where exact results are available and to more complicated geometries of practical interest. These examples include a tube with "fractal'' cross section and open channel flows. The calculations demonstrate the feasibility of the probabilistic method for pipe flow and other applications having an equivalent mathematical description (e.g., torsional rigidity of rods, membrane deflection). The example of flow through a fractal pipe shows an extended region of diminished flow velocity near the rough boundary which is similar to the suppressed vibration observed near the boundaries of fractal drums.

    Dermatofibroma with granular cells (1996)

    Notes: A new histologic variant of dermatofibroma, only briefly alluded to in dermatological literature is reported. This tumor was located in the back of a 24-year-old man. It was present for about 2 years and had a history of trauma 2 months before excision. The lesion showed similar characteristics to those of conventional dermatofibroma as well as the presence of groups of granular cells identical to those seen in granular cell tumors. It is important to recognize dermatofibroma with granular cells because it may be confused with a variety of benign or malignant soft tissue tumors containing similar granular cells that entail different significance or prognosis. The immunohistochemical study supports a granular cell change in a dermatofibroma instead of a granular cell tumor that has been traumatized, with secondary formation of a dermatofibroma reaction.

    Notes: The best conditions for the application of the predictor jump (PJ) method in the solution of the Laplace equation are discussed and some practical considerations for applying this new iterative technique are presented. The PJ method was remarked on in a previous article entitled "A new way for solving Laplace's problem (the predictor jump method)'' [J. M. Vega-Fernández, J. F. Duque-Carrillo, and J. J. Peña-Bernal, J. Math. Phys. 26, 416 (1985)].

    Notes: This paper presents a new method, that we call "the predictor jump,'' for driving to a faster solution of Laplace's equation. Some results obtained by applying this technique are compared with those that have been obtained by the traditional methods.

    Cutaneous angiomyolipoma (1996)

    Notes: Extrarenal angiomyolipomas are rare lesions. An angiomyolipoma located on the right ear lobe in a 49-year-old man is reported. Pathologic examination showed a well-circumscribed subcutaneous nodule, 2 cm in diameter. The components of the tumor were confirmed by immunohistochemistry. Reactivity for HMB-45 was negative. A review of the twelve published cases, including the present, reveals that the patients' age ranged from 33 to 77 years (mean 53.6); the male/female ratio was 11:1. The tumors were solitary, asymptomatic, noninvasive, located most commonly in acral skin or on the ear. The clinical impression is that of a cyst, a lipoma or a vascular tumor. Signs of tuberous sclerosis were absent in all cases. In contrast to the renal form, the cutaneous angiomyolipoma is a tumor differing in sex predominance, clinical associations, circumscription, solitariness, and HMB-45 immunoreactivity. Distinction from other mesenchymal lesions depends on recognition of traditional histologic criteria.

    Cutaneous lipomatous neurofibroma: characterization and frequency (2005)

    Notes: Background:  There are numerous variants of cutaneous neurofibroma reflecting its manner of growth and histologic composition. Lipomatous neurofibroma is the latest described variant with only eight cases reported.Methods:  A systematic study based on 320 consecutive specimens diagnosed of cutaneous neurofibroma was carried out. Conventional microscopy, immunohistochemistry, and statistical methods were used to determine the presence of fat cells, their amount, distribution, and frequency.Results:  Intratumoral fat was observed in 22 (6.9%) neurofibromas. All these were dermal neurofibromas. Intraneoplastic fat was divided into two groups: focal and diffuse (regularly interspersed). Eighteen tumors (5.6%) presented adipocytes focally intermingled with the spindle cells. There were four (1.3%) neurofibromas showing spindle cell proliferation with regularly scattered adipocytes. Lipomatous neurofibroma was more frequent located on head and neck than non-lipomatous neurofibroma ( p = 0.04). Neurofibromas without mature adipocytes were more frequently immunoreactive for CD34 compared with tumors showing intratumoral fat ( p = 0.02).Conclusions:  We suggest that both metaplasia and aberrant adipose differentiation from multipotential cells may result in lipomatous neurofibroma. Focal presence of adipose cells may be attributable to metaplasia as the pathogenic mechanism. The fatty tissue being intrinsic to the tumor structure in its diffuse form, the lesion represents a distinctive tumor of the peripheral nerve sheath.

    Cutaneous metastases as initial manifestation of dedifferentiated chondrosarcoma of bone. An autopsy case with review of the literature (2000)

    Notes: Metastases of chondrosarcoma to the skin are uncommon. We report a case of dedifferentiated chondrosarcoma that manifested as cutaneous metastases and had an outcome of three weeks. A 69-year-old male presented with two cutaneous nodules, one in the chest and other in the inguinal area. The punch biopsy of the latter showed a poorly differentiated mesenchymal metastatic tumor. Shortly before death, an X-ray revealed a proximal epiphyseal lesion in the right humerus, radiographically interpreted as chondrosarcoma. The autopsy showed this lesion to be a dedifferentiated chondrosarcoma whose nonchondroid mesenchymal part was akin, histologically and immunohistochemically, to the cutaneous metastases. While ten previous reports of chondrosarcoma metastatic to the skin are known, we believe that this is the first case to report the cutaneous metastases of the dedifferentiated variety. Furthermore, skin metastasis preceding the diagnosis of chondrosarcoma has not been previously reported. The fact that one part of this kind of tumor can be highly undifferentiated or, else, differentiated along lines not usually reminiscent of bone tumors, can make the diagnosis of such cases extremely difficult. Most chondrosarcomas metastatic to the skin arise in bones of the extremities, including the hand. The most common type of tumor is conventional chondrosarcoma. These metastases can be either single or multiple with a slight predilection for the head and neck region. Most patients die in a mean time of 6 months after the appearance of cutaneous metastases.
