1. PATCH STAGE
Mild epidermal hyperplasia with

of small- to medium-sized atypical
lymphocytes with cerebriform nuclear

MF PATCHES
EPIDERMOTROPISM:
Cerebriform lymphocytes exhibit
epidermotropism and are arranged
along the dermal-epidermal junction
in a single-file pattern or scattered
in the epidermis.
Pautrier’s microabscesses are small
intra-epidermal collections of cerebriform
lymphocytes & are pathognomonic for
MF. They might not be present in early
stages of MF
Eczematoid
2. PLAQUE STAGE:
The density of the neoplastic
cells within dermis increases
Exaggerated epidermotropism

CLINICAL PRESENTATION OF MF
MF often has a long natural history
Median duration from onset to diagnosis may be 5 years or more
Usually starts with scaly skin lesions that wax & wane over years
Biopsy at this stage is usually non-diagnostic
Patient may respond at this stage to topical steroid
Repeated biopsy is warranted if MF is suspected and biopsy is negative

Dear Professor Hoppe,
I am writing on behalf of a strong-willed 32 year old Iraqi Kurdish patient with the
diagnosis of mycosis fungoides, involving almost 20% of her body surface area.
Patient gives three years history of scaly skin lesions, not responding to topical
dermatological treatment. Recent histology sections showed the diagnosis
of early stage mycosis fungoides.
Patient desires consultation from Stanford, specifically asking for yourself.
I truly appreciate having an appointment for January 2007 with a formal
letter indicating the detail of the visit and the cost associated with the treatment.
After having the appointment letter from your hospital, we usually need
few months to process the visa to USA.
Looking forward to hearing from you.
Professor Anwar Sheikha, MD, FRCP, FRCPath.
MYCOSIS FUNGOIDES
SHEIKHA
Dear Professor Sheikha,
Thank you for your inquiry regarding possible consultation and treatment for
mycosis fungoides. We would be happy to see your patient at Stanford.
We have a comprehensive multi-disciplinary cutaneous lymphoma clinic that
includes dermatologists (Dr. Y. Kim is the Director), radiation oncologists,
medical oncologists, and dermatopathologists.
Our preference is to see all new patients in this clinic before making specific
recommendations for therapy. We employ a variety of topical and systemic
therapies for management and one of our major treatment programs is with
total skin irradiation.
Considering the special circumstances for this patient, to facilitate her visit
and treatment, it would probably be best while we are waiting for visa
clearance, etc. to be able to review the biopsy material. It might be simplest
if you request the slides and then forward them to me (R. Hoppe,
Department of Radiation Oncology, Room CC-G224, 875 Blake Wilbur Drive,
Stanford CA 94305). I will then obtain review from Stanford Pathology.
MYCOSIS FUNGOIDES
SHEIKHA
Assuming we confirm the diagnosis, we would be able to save some time once the
patient arrives. It is possible we may recommend treatment other than irradiation
(e.g., phototherapy or topical agents) that does not require staying at Stanford.
If that is the case, the expense would probably not be greater than several hundred
to a few thousand dollars, depending on other examinations (e.g., radiology, etc.)
that we may recommend. If we recommend a course of total skin irradiation,
the "list price" would total ~$76,000.
Our clinic will be meeting in January on January 11, 25, and 26 and we could
arrange an appointment for any of those dates.
In addition, I have taken the liberty of contacting Barbara Ralston in our Office of
Special Patient Services to facilitate these arrangements.
If you have any other questions, please feel free to contact me.
Sincerely,
Rich Hoppe
Chair, Radiation Oncology

TREATMENT OF MF
TOPICAL
CHEMOTHERAPY
TOPICAL NITROGEN MUSTARD “MECHLORETHAMINE"
Mechanism ??
10 to 20 mg
Per 100 cc
=
Effective
Choice of aqueous or ointment depends on convenience, preference & cost
Hypersensitivity is 30% with Aqueous solution & < 5% with ointment
MYCOSIS FUNGOIDES
SHEIKHA
Topical N2-Mustard is applied locally or to the entire skin at least daily
during the clearing phase.
After few weeks treatment may be applied to the affected region.
N2-Mustard may only be applied to the affected anatomical site if
the disease is really limited.
Treatment is continued on daily basis until the lesions are cleared
(6 months+)  3 to 6 months of maintenance therapy
If response is slow; increase N2-Mustard concentration or
frequency of application
Half will relapse after discontinuation of R/ but respond again
CR rate for limited patch or plaque stage “T1” is 70% to 80%
The median time to skin
clearance is 6 to 8 months
20% to 25% have durable
CR of > 10 years

CHEMOTHERAPY
TOPICAL
Carmustine
“BCNU"
Similar efficacy to N2- Mustard but it could be
absorbed & cause myelosuppression,
thus limiting its long-term use.
BCNU use could cause telangiectasias in areas exposed to the drug
MYCOSIS FUNGOIDES
PHOTOTHERAPY
SHEIKHA
TREATMENT OF MF
Ultraviolet Light (UV)  UVA or UVB wavelength ± Psoralen =
Psoralen is a photosensitizing agent
PUVA
The long-wave UVA has greater dermal penetration power
For early Limited disease UVB alone or Home UV phototherapy
(UVA & UVB) could be effective
PUVA is the most commonly used form of therapy for MF & SZS
It is effective in Psoriasis but has also been found to be effective in MF
PUVA is used 2-3 times/week during the clearance phase ( >6 months)
Reduce frequency in maintenance phase. For recurrence ↑ frequency again
Complete clearance rate with PUVA is 50% to 90% for patch & plaque stage
Less response for erythrodermic or tumor stage
MYCOSIS FUNGOIDES

COMPLICATIONS
ACUTE:
Nausea

TREATMENT OF MF
RADIATION
THERAPY
MF is an exquisitely radiosensitive neoplasm
Irradiation may be exploited in several ways
Individual plaques or tumors of MF may be treated to total
doses of 15 to 25 Gy in 1 to 3 weeks, with a high likelihood
of achieving long-term local control.
For the unusual patient with with unilesional or localized MF, local electron
beam therapy achieves the most efficient & complete clearance of the disease
Depth of penetration of electrons is controllable; this is of major advantage in MF
Depth of R/ with TSEBT is better than N2-Mustard or PUVA

REVISON
Various Cutaneous Manifestations of Mycosis Fungoides
Panel A shows patch-or-plaque MF affecting the lower trunk.
The patches are thin, slightly scaly, erythematous lesions typically greater
than 4 cm in diameter and distributed in sun-shielded areas such as those
covered by a bathing suit or intertriginous regions.
Plaques are thicker than patches.
Various Cutaneous Manifestations of Mycosis Fungoides
Panel B shows pagetoid reticulosis, a variant of mycosis fungoides that
typically consists of a single patch or plaque located in an acral area.
Various Cutaneous Manifestations of Mycosis Fungoides
Panel C shows syringotropic mycosis fungoides, which is manifested as
papules 1 to 3 mm in diameter distributed in the eccrine ducts, indicating the
propensity of lymphoma cells to accumulate in these locations.
Various Cutaneous Manifestations of Mycosis Fungoides
Panel D shows follicular mycosis fungoides, in which lesions characterized by
alopecia develop. In a similar variant, there is mucin deposition in the follicles.
Various Cutaneous Manifestations of Mycosis Fungoides
Panel E shows hypopigmented mycosis fungoides.
This variant is more noticeable in persons with dark pigmentation and may be
more common in childhood and adolescence than in adulthood.
Hypopigmentation to full depigmentation occurs in patches.
Various Cutaneous Manifestations of Mycosis Fungoides
Panel F shows erythrodermic mycosis fungoides.
This variant may evolve from patch-or-plaque mycosis fungoides and eventually
involve more than 80 percent of the body-surface area.
It may also arise spontaneously, as in the Sézary syndrome.
Various Cutaneous Manifestations of Mycosis Fungoides
Panel G shows the Sézary syndrome.
In its most florid form, the diffuse infiltration of the skin may produce the
exaggerated facial lines, resulting in "leonine facies."
The Sézary syndrome is also associated with atypical lymphocytes on the blood
smear.
Various Cutaneous Manifestations of Mycosis Fungoides
Panel H shows a mycosis fungoides tumor.
Such tumors define the T3 stage of disease and may arise at the site of plaques
or appear on their own, without being preceded by a patch-or-plaque lesion. The
vertical growth phase is accelerated, and tumors tend to appear more quickly
than plaques. Tumors not characterized by epidermotropism or previous mycosis
fungoides are sometimes called "non–mycosis fungoides cutaneous T-cell
lymphoma
