Brain infection can cause granulomas, hematomas, and abscesses. Subdivisions
The evolutionary history of the Eucestoda has been studied using ribosomal RNA, mitochondrial and other DNA, and morphological analysis and continues to be revised. "Tetraphyllidea" is seen to be paraphyletic; "Pseudophyllidea" has been broken up into two orders, Bothriocephalidea and Diphyllobothriidea. Hosts, whose phylogeny often mirrors that of the parasites (Fahrenholzs rule), are indicated in italics and parentheses, the life-cycle sequence (where known) shown by arrows as (intermediate host1 [→ intermediate host2 ] → definitive host). Alternatives, generally for different species within an order, are shown in square brackets. References

Cutaneous T-cell lymphoma (CTCL) is a class of non-Hodgkin lymphoma, which is a type of cancer of the immune system. Unlike most non-Hodgkin lymphomas (which are generally B-cell-related), CTCL is caused by a mutation of T cells. The cancerous T cells in the body initially migrate to the skin, causing various lesions to appear. These lesions change shape as the disease progresses, typically beginning as what appears to be a rash which can be very itchy and eventually forming plaques and tumors before spreading to other parts of the body. Signs and symptoms
The presentation depends if it is mycosis fungoides or Sézary syndrome, the most common, though not the only types. Among the symptoms for the aforementioned types are:  enlarged lymph nodes, an enlarged liver and spleen, and non-specific dermatitis. Cause
The cause of CTCL is unknown. Diagnosis
A point-based algorithm for the diagnosis for early forms of cutaneous T-cell lymphoma was proposed by the International Society for Cutaneous Lymphomas in 2005. Classification
Cutaneous T-cell lymphoma may be divided into the several subtypes. : 727–740  Mycosis fungoides is the most common form of CTCL and is responsible for half of all cases. A WHO-EORTC classification has been developed. Treatment
There is no cure for CTCL, but there are a variety of treatment options available and some CTCL patients are able to live normal lives with this cancer, although symptoms can be debilitating and painful, even in earlier stages.
