[Dermatomyositis as the first manifestation of small cell carcinoma: case report and literature review].

Dermatomyositis is an autoimmune inflammatory myopathy associated with dermatologic findings. Its association with neoplasms is widely reported and has been shown to be higher in lung cancer, particularly small-cell carcinoma, probably as it originates from neuroendocrine cell precursors, as well as breast and ovarian cancer. The low frequency of dermatomyositis makes it difficult to suspect the underlying lesions among the diagnostic possibilities of systemic diseases with cutaneous manifestations.

[Pleomorphic adenoma on heterotopic salivary inclusion: case report and literature review].

Heterotopic salivary gland tissue is the presence of salivary tissue outside of the salivary glands. It is an uncommon condition but it can be the source of the full spectrum of salivary gland diseases. We present a rare case of pleomorphic adenoma developing from heterotopic salivary gland tissue in an upper neck lymph node not related to the major salivary glands.
