case_images: Histopathology of the excised mass showed a tumor composed of haphazardly arranged spindle-shaped and oval cells in a predominantly fibrous background, interspersed with prominent dense bands of collagen that clamped residual glands (Figs. 4 and 5).

case_images: Histopathology of the excised mass showed a tumor composed of haphazardly arranged spindle-shaped and oval cells in a predominantly fibrous background, interspersed with prominent dense bands of collagen that clamped residual glands (Figs. 4 and 5).
case_images: Higher magnification showing a stroma infiltrated by numerous inflammatory cells composed of lymphocytes, plasma cells and eosinophils (haematoxylin & eosin stain, x400)

case_images: Fig6
case_images: The stroma was infiltrated by numerous inflammatory cells composed of lymphocytes, plasma cells and rare eosinophils (Fig. 6).
case_images: Immunohistochemical staining revealed the expression of smooth muscle actin (a) and ALK (b) by the neoplastic cells. Keratin highlights the residual glands (c). Ki-67 immunostaining showed a low proliferation index (d)
